Answer» A disc of mass $4 m$ is resting on a horizontal frictionless surface and pivoted at point $O$ as shown in the figure, perpendicular to its plane. A point object of mass $m$ , moving horizontally with velocity $v$ , hits the disc and sticks to it. Find the angular velocity of the system after the hit.
