A boy of mass 30kg is running with a velocity of "3 ms"^(-1) on ground just tangentially to a merry - go round which is at rest. It has radius R = 2m, a massess of 120 kg radius of gyration is 1m. If the boy suddenly jumpes on to the merry -go - round, the angular velocity acquired by the system is
