A small ball of mass m with initial speed u horizontally collides with a rigid rod of length D and mass M 18m, on its upper edge. After the collision, the ball returns with horizontal speed c/2 and the rod starts to rotate with angular velocity e around its center of mass. Find the angular velocity of the rod after the collision with respect to its center of mass) 20 3D
