A ball of mass $\displaystyle 0.15$ kg hits the wall with its initial speed of $\displaystyle 12 \mathrm{~ms}^{-1}$ and bounces back without changing its initial speed. If the force applied by the wall on the ball during the contact is $\displaystyle 100$ N , calculate the time duration of the contact of ball with the wall.
Official answer
(2)
0.$\displaystyle 036$ s
