Solve the all parts of given problemproblem a soft tennis, Ask an Expert

Academics

Solve the all parts of given problem:

Problem: A soft tennis ball is dropped onto a hard floor from a height of 1.90 m and rebounds to a height of 1.42 m. (Assume that the positive direction is upward.)

Part I: Calculate its velocity just before it strikes the floor in m/s?

Part II: Calculate its velocity just after it leaves the floor on its way back up in m/s?

Part III: Calculate its acceleration during contact with the floor if that contact lasts 3.50 ms in m/s².

Part IV: How much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid in m?

Any help I can get on this question is greatly appreciated! I'm not too familiar with this question.
