A circular disc M R can freely rotate in vertical x y plane about a fixed axis perpendicular to the plane of the disc and passing through a point A on periphery of the disc as shown in figure A point mass m moving with velocity vo collides with stationary disc at its central line elastically and particle stops after collision Disc M R m Vo Axes A If w is the angular speed of disc after collision then v Rw If w is the angular speed of disc after collision then v 2wR Linear momentum of system is conserved just before and just after collision Angular momentum of system about hinge point is conserved just before and just after collision
