A playground merry-go-round has a radius of 4.30 m and a moment of inertia of 245 kg/m^2 and turns with negligible friction about a vertical axle through its center.

A)A child applies a 25.0 N force tangentially to the edge of the merry-go-round for 20.0 sIf the merry-go-round is initially at rest, what is its angular velocity after this 20.0 s interval?

= rad/s

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

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