A tennis ball with a speed of 24.9 m/s is moving perpendicular to a wall. After striking the wall, the ball rebounds in the opposite direction with a speed of 15.1 m/s. Take "toward the wall" to be the positive direction.
If the ball is in contact with the wall for 0.0108 s, what is the average acceleration of the ball while it is in contact with the wall?
Answer in units of m/s/s.

0m/s - 24.9m/s - 15.1m/s = -40m/s total change of speed
-40m/s / 0.0108s = -3703.7 m/s^2 average acceleration
