Question

The homogeneous sphere with mass m is held 1 m above the horizontal plane and rotates with an angular velocity of 30 rad/s clockwise. The sphere is then released and falls impacting the ground below at A. Determine the velocity of the centre of mass of the sphere after it bounces. Assume the ground is rough so no slipping occurs, and the coefficient of restitution is 0.9.
