A tennis ball with a speed of 11.4 m/s is thrown perpendicularly at a wall. After striking the wall, the ball rebounds in the opposite direction with a speed of 8.64 m/s. If the ball is in contact with the wall for 0.0104 s, what is the average magnitude of acceleration of the ball while it is in contact with the wall?

a = (-8.64-11.4)/0.0104 = 1926 m/s2
