A 90-kg merry-go-round of radius 2.0 m is spinning at a constant
speed of 20 revolutions per minute. A kid standing on the ground
decides to bring the merry-go-round to rest and applies a force of
10.0 N tangentially to the merry-go-round. If the merry-go-round is
modelled as a solid cylinder, (A) calculate its moment of inertia.
(B) What is the angular acceleration of the merry-go-round? (C) How
many revolutions will the merry-go-round complete until it finally
stops?

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?
