Two billiard balls have equal masses and collide elastically, meaning no kinetic energy is lost in the collision. (a) Suppose one ball (the 8 ball) is at rest and the other ball (the cue ball) moves toward it with speed v0.

Explain how the energy of rubber ball is tranforned as it roll down a ramp. give evidence that the energy of the og the ball remains the same at all points on the ramp
