Hello, I'm starting to study physics, and I have a problem that I have puzzled me for long... here it is. any help appreciated. thanks in advanced.
A tennis ball with a speed of 23.6 m/s is
thrown perpendicularly at a wall. After strik-
ing the wall, the ball rebounds in the opposite
direction with a speed of 14.6 m/s.
If the ball is in contact with the wall for
0.014 sec, what is the average acceleration of
the ball while it is in contact with the wall?
