A playground merry-go-round has radius 3.00 m and moment of inertia 2600 kg - m about a vertical axle through its center, and it turns with negligible friction. Part A A child applies an 21.5 N force tangentially to the edge of the merry-go-round for 24.0 s. If the merry-go-round is initially at rest, what is its angular speed after this 24.0 s interval? w = 0.595 rad/s Submit Correct Part B How much work did the child do on the merry-go-round?
