A tennis ball is dropped from 1.7 m above the ground. It rebounds to a height of 0.955 m.

With what velocity does it hit the ground?

The acceleration of gravity is 9.8 m/s^2 (Let

down be negative.)

Answer in units of m/s

With what velocity does it leave the ground?
Answer in units of m/s.

If the tennis ball were in contact with the
ground for 0.0135 s, find the acceleration
given to the tennis ball by the ground.
Answer in units of m/s^2
