A soft tennis ball is dropped onto a hard floor from a height of 2.00 m and rebounds to a height of 1.59 m. (Assume that the positive direction is upward.)(a) Calculate its velocity just before it strikes the floor.   m/s (b) Calculate its velocity just after it leaves the floor on its way back up.   m/s (c) Calculate its acceleration during contact with the floor if that contact lasts 3.50 ms.   m/s2 (d) How much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid?  m
