A soft tennis ball is dropped onto a hard floor from a height of 1.60 m and rebounds to a height of 1.14 m. (Assume that the positive direction is upward.) (A) Calculate it's velocity just before it strikes the floor in m/s (B) Calculate it's velocity just after it leaves the floor on its way back up in m/s (C) Calculate it's acceleration during contact with the floor if that contact lasts 3.50 ms in m/s ^2 (D) How much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid? In m
