A playground merry-go-round has radius 2.50mand moment of inertia 2800kg?m2 about a vertical axle through its center, and it turns with negligible friction.

Part A A child applies an 18.0N force tangentially to the edge of the merry-go-round for 24.0s . If the merry-go-round is initially at rest, what is its angular speed after this 24.0s interval?

Part B How much work did the child do on the merry-go-round?

Part C What is the average power supplied by the child?
