A uniform rod of mass m and length 3r is free to rotate about a horizontal axis through O A disc of mass m radius r is free to rotate about another horizontal axis fixed to other end of the rod say C r 1 2 m The system is released from rest when rod is horizontal What is the velocity of particle at A in m s when rod becomes vertical m 3r m
