A tennis ball with a velocity of 24.4 m/s

is thrown perpendicularly at a wall. After

striking the wall, the ball rebounds in the

opposite direction with a speed of 16 m/s.

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?

Answer in units of m/s

acceleration=changevelocty/time=(24.4+16)/.013 m/s^2

24.4+16? If it's the change of velocity, wouldn't it be 24.4-16?
