A tennis ball with a speed of 25.9 m/s is
moving perpendicular to a wall. After striking
the wall, the ball rebounds in the opposite
direction with a speed of 21.3157 m/s.
If the ball is in contact with the wall for
0.0133 s, what is the average acceleration of
the ball while it is in contact with the wall?

Divide the velocity change by the time interval. Note that the bounceback velocity is negative.

Acceleration = [25.9 -(-21.3157)]/0.0133
= 3550 m/s^2
