Concept

Problem: A tennis ball with a speed of 10 m/s is moving perpendicular to a wall. After striking the wall, the ball rebounds in the opposite direction with a speed of 7.69 m/s. If the ball is in contact with the wall for 0.0122 s, what is the average acceleration of the ball while it is in contact with the wall? Take “toward the wall” to be the positive direction.
