A playground merry-go-round has a radius of 4.20m and a moment of Inertia 240 kgm^2 and turns with negligible friction about a vertical axis through its center. A child applies 25.0 N force tangentialy to the edge of the merry-go-round for 18.0 s. If the merry-go-round is initially at rest, what is its angular velocity after this 18.0s interval? How much work did the child do on the merry-go-round? What is the average power supplied by the child?
