A superball of mass M and a marble of mass m are dropped from a height h with the marble just on top of the superball. A superball has a coefficient of restitution of nearly 1 (i.e., its collision is fundamentally elastic). Ignore the sizes of the super ball and the marble. The superball collides by the floor; rebounds, and smacks the marble, which moves back up. How high does the marble go if all the motion is vertical? How high does the superball go?
