Question

A tennis ball with a speed of 5.0 m/s is thrown perpendicularly at a wall. After striking the wall, the ball rebounds in the opposite direction with a speed of 3.0 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 1

Ft = m(final velocity) - m(initial velocity)

F = ma so equation changes to

mat = m(final velocity) - m(initial velocity)

plug in values and solve for 'a'
