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? 1) [25...

Problem 3: A merry-go-round can be considered a uniform disk of mass 145 kg and radius 2.10 m free to rotate about a frictionless axis through its center. A 40.0 kg child stands at the edge and the system is initially rotating at 0.300 rad/sec. The child begins to walk around the edge of the merry-go-round with a velocity of 0.250 m/s relative to the ground in the direction of the rotation. What is the angular velocity of the merry-go-round...
