Aplayground merry-go-round has radius 2.40 m and moment of inertia 2100 kgm2 about a vertical axle through its center, and it turns with negligible friction. (a) a child applies an 18.0-n force tangentially to the edge of the merry-go-round for 15.0 s. if the merry-go-round is initially at rest, what is its angular speed after this 15.0-s interval? (b) how much work did the child do on the merry-go-round? (c) what is the average power supplied by the child?
