Asmall ball of mass m is placed on top of a "superball" of mass m, and the two balls are dropped to the floor from height h. how high does the small ball rise after the collision? assume that col- lisions with the superball are elastic, and that m ≪ m. to visualize the problem, assume that the balls are slightly separated when the superball hits the floor. (if you are surprised by the result, try demonstrating the problem with a marble and a superball.)
