A steel ball is dropped onto a hard floor from a height of 1.55 m and rebounds to a height of 1.45 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.
(c) Calculate its acceleration during contact with the floor if that contact lasts 0.0800 ms.
m/s2
