A tennis ball with the speed of 13.6 m/s is moving perpendicular to a wall. After striking the wall, the ball rebounds I the opposite direction with a speed of 12.2264 m/s. If the ball is in contact with the wall for 0.0145 s, what is the average acceleration of the ball while it is in contact with the wall? Take “toward the wall” to be positive direction. Answer in units of m/s^2
