Example - Elastic Collision Suppose I have 2 identical bumper cars. One is motionless and the other is approaching it with velocity vi. If they collide elastically, what is the final velocity of each car? Note that this means m=m2= m =0 Physics 121: Lecture 16, Pg 11Physics 121: Lecture 16, Pg 11 Example - Elastic Collision Suppose I have 2 identical bumper cars.
