The SetupTwo balls are dropped from a height of h1. The balls are stacked one on top of the other. The bottom ball of mass m1 is more massive than the second ball of mass m2. After the balls are dropped the heavier ball will collide with the floor and the lighter (top ball) will collide with the heavier ball.Please give an expression for the maximum height (h2) which the lighter ball (m2) will reach as a function of m2 m1 h1 and possibly g (acceleration due to gravity)Assumptions1)The balls can be treated as points2)All collisions are elastic.Please state which principals you will use (i.e conservation laws) and show all you work
