A playground merry-go-round has a radius of 4.50m and a moment of inertia of 240kg?m2 and turns with negligible friction about a vertical axle through its center.

Part A A child applies a 25.0N force tangentially to the edge of the merry-go-round for 22.0s . If the merry-go-round is initially at rest, what is its angular velocity after this 22.0s interval? ?= rad/s

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

Part C What is the average power supplied by the child? P=?W
