A soft tennis ball is dropped onto a hard floor from a height of1.55m and rebounds to a height of1.10m. (Assume that the positive direction is upward.)

(a)Calculate its velocity (in m/s) just before it strikes the floor. m/s

(b)Calculate its velocity (in m/s) just after it leaves the floor on its way back up. m/s

(c)Calculate its acceleration (in m/s²) during contact with the floor if that contact lasts 3.50 ms. m/s²

(d)How much (in m) did the ball compress during its collision with the floor, assuming the floor is absolutely rigid? m
