Aplayground merry-go-round has radius 2.10m and moment of inertia 2500kg*m^2 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 16.0s . if the merry-go-round is initially at rest, what is its angular speed after this 16.0s interval?

in 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?

i understand the jist of the question but am stuck on where to start
