And Another Cool Physics Problem
Two balls, one of mass m and the other of mass 2m are dropped from a height h, as shown. The lighter mass is on top, and the radius of the heavier ball is R. All collisions are perfectly elastic, and air resistance can be ignored. How high above the floor will the lighter mass reach after the rebound?
