Question 1165532: A tennis ball with a speed of 22.2 m/s is
moving perpendicular to a wall. After striking
the wall, the ball rebounds in the opposite
direction with a speed of 14.9184 m/s.
If the ball is in contact with the wall for
0.00965 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.
Answer in units of m/s^2

By the DEFINITION, the acceleration is the CHANGE of SPEED divided by the time


    acceleration = %2822.2-%28-14.9184%29%29%2F0.00965.


You do the calculation.
