A merry-go-round is a playground ride that consists of a large disk mounted to that it can freely rotate in a horizontal plane. The merry-go-round shown is initially at rest, has a radius R- 1.3 meters, and a mass M- 216 kg. A small boy of mass m-46 kg runs tangentially to the merry-go-round at a speed of v 1.6 m/s, and jumps on. andomized Variables R 1.3 meters M-216 kg m 46kg v- 1.6 m/s Otheexpertta.com 17% Part (a) Calculate the moment of inertia of the merry-go-round, in kg-m2 17% Part (b) Immediately before the boy jumps on the merry go round, calculate his angular speed (in radians second) about the central 17% Part (c) Immediately after the boy Jumps on the merry go round, calculate the angular speed in radians second of the merry-go-round 17% Part (d) The boy then crawls towards the center of the merry-go-round along a radius.

He decides to crawl to the outer edge of the merry-go-round and jump off. Somehow, he manages to jump in such a way that he hits the ground with zero velocity with respect to the ground. What is the angular speed in radians/second of the merry- go-round after the boy jumps off?
