The radius of a park merry-go-round is 2.2 m. To start it rotating, you wrap a rope around it and pull with a force of 260 N for 12 s. During this time, the merry-go-round makes one complete rotation.
(a) Find the angular acceleration of the merry-go-round.
(b) What torque is exerted by the rope on the merry-go-round?
(c) What is the moment of inertia of the merry-go-round?
