Asmall ball of mass m is dropped immediately behind a large one of mass m from a height h mach larger then the size of the balls. what is the relationship between m and m if the large ball stops at the floor? under this condition, how high does the small ball rise? assume the balls are perfectly elastic and use an independent collision model in which the large ball collides elastically with the floor and returns to strike the small ball in a second collision that is elastic and independent from the first.
