Grounded for Life!!
Let's say that someone you know is driving WAY too fast on the freeway (obviously, you personally are much too smart to do anything so foolhardy and dangerous!). Ultimately, your friend's parents will find out he's driving at 80 mph no matter what. He can't escape getting busted! BUT, from the options below, choose which POV/frame of reference he would want his parents to have so his velocity seems the lowest relative to them.Choose one by
voting in the poll to the right,
and add a comment to explain WHY your choice is best...
The parents driving 60 mph toward him (on the other side of the freeway, of course).
The parents driving 60 mph in the same direction on his side of the freeway.
The parents sitting along the freeway watching him drive by. (External)

ReplyDeleteI think the parents driving in the same direction as him would make the velocity seem the lowest. This is because the first choice (driving at him) will make the parents POV seem like the kid is going 140 m/hr. In the third one, the parents can see the kids true speed of 80 m/hr. But the second one will show from the parents POV that the kid is slowly passing the parents. Therefore, the parents driving in the same direction at 60 m/hr would be the best choice.
ReplyDeleteI had originally voted for the parents position as oncoming traffic, but have realized that from that POV, the two cars would be moving at each other at 80 MPH + 60 MPH - leading to a POV of my "friend's" car moving at 140 MPH. Thats very fast. Whereas if the two cars are driving alongside each other with the friend going at 80 MPH and his/her parents at 60, the kid will only be 20 MPH faster. Also, theres less of a chance of a full-frontal eye-contact moment, so the kid might get away with speeding this time. :)
ReplyDeleteI put driving in the same direction because even if the kid is driving 80 mph and the parents are driving 50mph the kid will only look like he is going 30 mph. Moreover if the parents are driving towards the kid the kid will look like he is going 80mph + the speed of the parents' car. Also if the parents are sitting along side the freeway they will see that the actual speed of the kid's car.
ReplyDeleteI voted for the parents to be driving in the same direction as their child. When one is driving around the same speed next to someone, from one cars perspective, it looks as if the other car is not going very fast. If the parents are driving 60mph and the child driving 80mph, then it will appear as though he was only driving 20mph.
ReplyDelete"The parents driving 60 mph in the same direction on his side of the freeway.", because the speed difference of the velocities will be 20 mph, and if the parents lacked even the slightest amount of common sense, to them, it would look like the kid is only going 20 mph.
ReplyDeleteI personally believe that the parents driving 60 mph toward him on the other side of the freeway would make the most sense. If the parents are driving on the other side of the freeway it would be extremely hard for them to acknowledge that their son is going fast.
ReplyDeleteThe parents driving 60 mph in the same direction on his side of the freeway.
ReplyDeleteI vote this because if the parents were driving on the other side of the freeway the gap between them and the child will be closing in at 140mph, making it look like the child is going at 140mph on the other side. Furthermore, watching externally they can see that the child is speeding by other cars at 80mph, therefore the best one is if the parents are driving the same direction because it'd be fairly hard for them to tell at what speed the kid is driving at.
The apparent velocity is dependent on the velocity and the direction of the frame of reference, therefore the goal of the driver is to reduce the apparent velocity as much as possible. If the driver were driving the opposite direction of his parents, then his speed would look as if it were 140mph and that is pretty high. If the parents' frame of reference were not moving (an external POV), then the apparent velocity is the actual velocity, 80mph. This leaves the option of the parents driving alongside the driver; because the parents and the driver are driving in The same direction, therefore the relative velocity only appears to be 20 mph. Driving alongside the driver makes it appear as though the driver is only driving at 20 mph relative to them, making it the lowest relative (to the parents) speed.
ReplyDeleteAlthough they wouldn't be traveling at the same exact speed (the kid 80 mph, his parents 60 mph), if the irresponsible driver and his parents were both driving in the same direction on the same side of the freeway, then their difference in rate would relatively not appear as drastic to each other. For example, if his parents were to act as the "3rd person" and simply watch their son drive by while they sat idly in their car, they would clearly see his reckless driving and he would thus get "grounded for life." Further, if they both drove towards each other, their speeds would only combine and seriously damage the vehicles at the "moment of impact," due to the intense amount of force.
ReplyDeleteThe kid would definitely want his parents to be driving along side him going 60 mph because from their frame of reference they would see themselves as "Zero The Hero" going 0 mph and their son going at only 20 mph. The other choice where the parents are going the opposite direction at 60 mph will make the child's car appear to be going even faster than 80 mph, appearing to be at 140 mph which definitely would lead to some serious grounding for the child. Finally, the choice to have the child's parents be in the third person perspective where they could see the "truth" would also not be good. Although it would be the most honest choice, for the child's sake he should opt for choice two avoiding the wrath of his parents!
ReplyDeleteIf the kid is driving along side his parents at 80 mph, while the parents are driving at 60 mph, POV would make it appear as if the kid was traveling at 20 mph. Due to their frame of reference, they would feel as if they were traveling at 0 mph. This would be a much better option that going head on with the kid or being stopped while the kid is driving. In each of the other scenarios, the kid would appear (to the parents) to be traveling at rates higher than 20 mph.
ReplyDeleteThe kid would want the parents to be driving in the same direction. If the parent's were driving in the same direction then the kid would look like he was going 20 mph. Since the parents are driving 60 mph and they are "Zero the Hero." The kid at 80, is only 20 more mph then 0.
ReplyDeleteThe kid wants his parents to be driving in the same direction because if they are going 60 and the kid is going 80 mph the difference is 20 mph. So the parents frame of reference is only 20 mph from the kid.
ReplyDeleteI say that if the child's parents should be driving towards him because since they are both driving towards each other their POV is that they are just getting closer and closer to each other quickly which gives the idea that they are going at the same speed because you wouldn't be able what speed they are at rather than driving next to each other because having a 20mph gap in speed may not sound that much but is actually a great amount of speed. There would be a solid few 10+ feet space between them and that is easily differentiated.
ReplyDeleteFor the driver's sake, he or she would want his parents to be driving in the same direction as him. This is because if the parents were driving in the same direction from the frame of reference they would see themselves as "Zero the Hero". Whilen the kid is going 80 MPH on the freeway, he would only be 20 mph faster than his parents at that specific frame of reference.
ReplyDeleteMy friend would want his parents to be driving the same direction as him in order for them to recognize that he is speeding in the least dramatic way. Although he is going 80 MPH, since his parents are going 60 MPH next to him, it only seems like he is going 20 MPH. If they were on the side of the road, they would recognize the truth that he is going 80 MPH. If they were driving toward him, they would think of him as driving their speed AND his speed toward them, since they see themselves as zero (so they'd think he's going 140 MPH). Therefore, the parents' POV that looks like the child is going slowest is if they are driving alongside him.
ReplyDeleteIt would definitely be most favorable for my irresponsible friend's parents to be driving in the same direction as him on the freeway at 60mph. Although driving at 80mph on the freeway would not be safe, the 20mph difference would seem much less to the parents, who from their frame of reference, would see themselves as "Zero the Hero." If the parents were driving 60mph toward their child on the other side of the freeway, because of the two speeds going in opposite directions, their child would appear to be going at 140mph, a combination of both speeds. If the parents were to sit on the side of the freeway and watch their child drive by at 80mph, they would witness their child's speed accurately. My friend would get busted in all three cases, but his velocity would seem lowest relative to his parents if they were to drive alongside him.
ReplyDeleteIf the parents of the kid were going 0 mph, the misbehaving punk would go by them at 80mph; however, if the parents would be going at 60 mph along side with him, the kid would only be going 20mph faster than them, making the difference of speed less dramatic.
ReplyDeleteIf both you and your parents are going the same way and you are going 80 and they are going 60 it will seem to them that you are only going 20 miles per hour because you have to subtract 80-60 because you are going the same way. However if you are going 80 towards your parents while they are going 60 it will seem as though you are going 140 miles per hour. lastly if your parents saw you from a third person perspective they would clearly be able to tell you are going 80 miles per hour.
ReplyDeleteIf your parents were driving 60 mph towards you, it would seem like you were going 140 mph because from their point of view they aren't moving. Also, if your parents were sitting on the side of the freeway, they could clearly see you driving 80 mph. Finally, if you and your parents were driving in the same direction, it would seem like you were only driving 20 mph (80-60) away from them; therefore, driving at 80 mph in the same direction as your parents would seem the slowest from their point of view.
ReplyDeleteThe best choice would be driving in the same direction as him because their POV in their car going at 60 seems like 0 and they would only be able to tell a 20 mph(80-60) speed from him/her. If they were driving in the other dierection, towards him/her than it would seem as if he was going 140 mph(80+60)for the pov of oncoming traffic adds to the speed of which you are actually going. Lastly, the outside pov would actually display his real speed of 80 mph(80+or-0) for the parents would not be moving at any speed.
ReplyDeleteI think the best option would be the parents driving in the same direction as the reckless driver because in the parents POV the car going at 60 to them feels like 0. In this instance the parents would only be able to conclude the child going a 20 mph distance between them. However, if the parents were going in opposite directions it would seem like the kid is going 140 mph based on there POV.
ReplyDeleteI believe the best answer would be that the parents driving in the same direction as their child would get him/her in the least amount of trouble because they will only feel as if they have a 20mph difference between their cars (seeing as they are going 60). If the parents had an external POV they would see that the car is going 80mph (much too fast) and if they were driving towards each other their speeds would accumulate and it would seem as if their child was going 140.
ReplyDeleteI voted that driving in the same direction would make my friend look like he is going slower than they were. I believe this because when going at a constant speed would seem like the car was still and the car going 80 would only seem like it was going 20 because the car going 60 would feel like "zero the hero".
ReplyDeleteI think going in the same direction as their child will give the parents a sense of going about the same speed. Since my friend is going 80 mph and his parents are only going 60 mph, the 20mph doesn't seem like that big of a difference because of zero the hero. If they were on the outside in a third person perspective, they would definitely realize how fast their son is driving.
ReplyDeleteAt first I thought that the better position for my friend's sake would be the parent's on the opposite side of the freeway, because i thought it would be more difficult to tell the speed at which he was going. However, i realized that when I am on the freeway and the cars on the other side pass by I hear a 'whoosh' and it seems like they are traveling much faster than we are. Therefore, it would be beneficial for my friend for his parents to be going in the same direction because the difference would only be 20 mph, making it seem less extreme.
ReplyDeleteThe boy would want his parents to be driving 60 m/h in the same direction on his side of the freeway. Which will allow his velocity to appear the lowest. In this case, the boy will only appear to be going 20 m/h to his parents. If he were to be driving towards his parents on the other side of the free way, it would make the boy appear as if he was going 140 m/h, which would definitely not make his parents too happy. Lastly, if the parents were sitting along the freeway watching him drive by, they would be able to see that the boy was indeed going 80 m/hr.
ReplyDeleteAs we discussed in class earlier this week, while driving your point of view suggests that you are moving at 0 mph. Therefore, if my friend is driving towards his parents who are driving at 60 mph, there point of view would suggest that he is driving at 140 mph, which is untrue. If his parents watch from the side of the freeway with a third-person, external point of view, then they will see the truth that he is driving at 80 mph. If he drives alongside his parents, his parents will see that he is driving 20 mph faster than them. However, since they think they are at 0, in their eyes he is driving at 20 mph instead of 60, making this the best option for my friend.
ReplyDeleteSo, when two objects are coming towards each other from a first person POV, it seems as though the other object is coming at a faster rate depending on speed. Also, if a person is watching the object travel, that too will seem as though it were traveling at a fast rate. Therefore, the friend would most likely want his/her parents to be driving 60mph in the same direction because it will not seem as fast compared to the other scenarios.
ReplyDeleteThe parent going in the same direction would be the best way of trying to avoid getting in trouble, because if the parents were not focusing on the speedometer, the kid would look like he is going at 20 miles an hour, which is much less than a parent standing on the freeway (oddly) and then watching the kid go 80. This would be able to deceive the parent's perception of the matter if they were going 60 MPH in the same direction.
ReplyDeleteThe best vote is the one where the parents are driving towards their child. This POV makes the object approaching seem slower than it actually is because of the person's point of view is from the opposite direction. If they parents were driving next to the child they would see how fast he is going if they themselves decided to slow down. The other option where they are watching their child drive by is even worst for the child because then the parents will completely be able to see how fast the son is on the freeway.
ReplyDeleteParents driving 60 in the same direction because it would seem as if he is slowly pulling away from them. Iit would be evident that he is moving faster than they are, but them traveling in the same direction would give the illusion that he is not traveling a lot faster.
ReplyDeleteHis parents driving at 60 miles per hour in the same direction would make it look like if he was going not that fast because if the friend is driving at 80 and his parents are driving at 60 it would look as if he was going 20 mph more. If his parents were driving toward him on the other side of the freeway at 60 mph, as the first answer choice says, the perspective he and his parents would get would be a high speed illusion, it would look as if he was going at 140 mph. In comparison to the third answer choice, he would seem as if he was going really fast, which he was. It would be too obvious that he is driving at 80mph and his parents immediately would notice.
ReplyDeleteHe would want his parents to be driving at 60mph in the same direction. This would make that it look like he was only going 20mph! (80-60=20). If his parents were driving toward him it would look like he was going 140mph (60+80=140). If his parents were watching from the side it would look like he was going 80mph which he is; this would be the third person view.
