Question

A 24.5-kg child is standing on the outer edge of a merry-go-round which has moment of inertia 989 kg • m2 and radius 2.40 m. The entire system is initially rotating at 0.180 rev/s. Find the angular velocity if the child moves to a final position 1.10 m from the center of the merry-go-round. [hint: similiar to the spinning ice-skater problem]
