Ineed attacking this problem a steel ball is dropped onto a hard floor from a height of 1.95 m and rebounds to a height of 1.87 m (assume positive direction is upward)
a. caculate it's velocity just before it strikes the floor
b. calculate it's velocity just after it leaves the floor on its way back up
c. calculate it's acceleration during contact with the floor if that contact lasts .0800ms
d. how much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid
