A playground merry-go-round has radius 2.10m and moment of inertia 2200kg*m^2 about a vertical axle through its center, and it turns with negligible friction.

1: A child applies an 24.0N force tangentially to the edge of the merry-go-round for 17.0s. If the merry-go-round is initially at rest, what is its angular speed after this 17.0s interval?

2: How much work did the child do on the merry-go-round?

3: hat is the average power supplied by the child?
