A soft tennis ball is dropped onto a hard floor from a height of 1.55 m and rebounds to a height of 1.12m. (Assume that the positive direction is upward.) (a) Calculate its velocity (in m/s) just before it strikes the floor. (c) Calculate its acceleration (in m/s2) during contact with the floor if that contact lasts 3.70 ms. (d) How much (in m) did the ball compress during its collision with the floor, assuming the floor is absolutely rigid?
