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