The radius of a park merry-go-round is 2.4 m. To start it rotating, you wrap a rope around it and pull with a force of 260 N for 11 s. During this time, the merry-go-round makes one complete rotation.
(a) Find the angular acceleration of the merry-go-round.
rad/s2
(b) What is the magnitude of the torque exerted by the rope on the merry-go-round?
N·m
(c) What is the moment of inertia of the merry-go-round?
kg·m2
