A tennis ball with a velocity of +9.6 m/s to the right is thrown perpendicularly at a wall. After striking the wall, the ball rebounds in the opposite direction with a velocity of -5.8 m/s (to the left). If the ball is in contact with the wall for 0.013 s, what is the average acceleration of the ball while it is in contact with the wall?
