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