Consider two balls A and B that are stacked one on top of the other and dropped from rest from a height h. Let eAG = 1 be the COR for the collision of ball A with the ground, and let eAG = 1 be the COR for the collision between balls A and B. Finally, assume that the balls can move only vertically and that mA ≫ mB, that is, that mB/mA ≈ 0. Model the combined collision as a sequence of impacts, and predict the rebound speed of ball B as a function of h and g, the acceleration due to gravity.
