Two small rubber balls are dropped fromrest at a height h above a hard floor. When the balls are released, thelighter ball (with mass m) is directly above the heavier ball (withmass M). Assume the heavier ball reaches the floor first and bounceselastically; thus, when the balls collide, the ball of mass M is movingupward with a speed v and the ball of mass m is moving downwardwith essentially the same speed. In terms of h, find the height towhich the ball of mass m rises after the collision. (Use the resultsgiven in Problem 83, and assume the balls collide at ground level.)
