A solid sphere has linear velocity 4m/s and angular velocity 9rad/s as shown.Ground on which it is moving is smooth.It collides elastically with a rough wall of coefficient of friction n radius of sphere = 1m and mass = 2 kg if the sphre rolls without slipping after the collision then n is Ans:1/4 What is the net linear impulse imparted by the wall on the sphere during impact? Ans : 4(14) 1/2 Ns
