(4) A playground ride, known as merry-go-round, consists of a disk with a mass of 40.0 kg and a radius of 1.80 m mounted on a frictionless axle. The frictionless axle is a vertical cylinder of radius kg, and has the same rotational axis as the disk. A child with a mass of 3.50 m/s on a line tangential to the outer rim of the disk and jumps onto the outer edge of the ride while it is at rest...

A merry-go-round, which may be approximated as a solid disk of
mass 90.0 kg and radius 2.00 m, is originally at rest but free to
rotate in the horizontal plane about its center. A child applies an
external force of 20.0 N tangentially to the outer edge of the
merry-go-round, for a duration of 15.0 s.
(a) What is the final angular velocity of the merry-go-round?
(b) What is the average power supplied by the child in the
process?
