Car "1" is pushed at a velocity of 5m/s Car "1" is pushed at a velocity of 5m/s toward Car "2" (car 2 is not moving). When they hit, Cart 1 bounces back a .5m/s and car 2 moves at 5.5m/s. Is that possible? Why or why not? I think that it's not possible, but i'm not sure why. Maybe b/c energy was gained somehow for car 2 to bounce back faster, which is not possible. How do i prove that?
