Center Of Mass

A ball of mass \(0.15 \mathrm{~kg}\) hits the wall with its initial speed of \(12 \mathrm{~ms}^{-1}\) and bounces back without changing its initial speed. If the force applied by the wall on the ball during the contact is \(100 \mathrm{~N}\), calculate the time duration of the contact of ball with the wall.
