66.In a playground there is a merry-go-round of mass 120 kg and radius 4 m. The radius of gyration is 3m. A child of mass 30 kg runs at a speed of 5 m per second tangent to the rim of the merry-go-round when it is at rest and then jumps on it. Neglect friction and find the angular velocity of the merry-go-round and child (a) 0.2 rad /sec (b) 0.1 rad /sec (c) 0.4 rad /sec (d) 0.8 rad /sec
