Question

(1096) Problem S: 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-1.1 meters, and a mass M- 221 kg. A small boy of mass m 49 kg runs tangentially to the merry-go-round at a speed of v1.7m/s, and jumps on. Randomized Variables - 1.1 meters M= 221 k v=1.7ms Otheexpertta.com @theexpertta.com-tracking id Service. copying this information to any solutions sharing website is strictly forbidden.

What is the angular speed in radians second of the merry-go-round when the boy is half way between the edge and the center of the merry go round? 17% Part (e) The boy then crawls to the center of the merry-go-round. What is the angular speed in radians second of the merry-go-round when the boy is at the center of the merry go round? -Δ 17% Part (f) Finally. the bov decides that he has had enough fun. He decides to crawl to the outer edge of the merry-go-round and iump 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!
