A teenager pushes tangentially on a small hand-driven merry-go-round and is able to accelerate it from rest to a frequency of 14 rpm in 10.9 s . Assume the merry-go-round is a uniform disk of radius 2.0 m and has a mass of 670 kg , and two children (each with a mass of 30 kg ) sit opposite each other on the edge.
a.) Calculate the torque required to produce the acceleration, neglecting frictional torque.
b.) What force is required at the edge?

Three children are riding on the edge of a merry-go-round that has a mass of 105 kg and a radius of 1.70 m. The merry-go-round is spinning at 18.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the 28.0 kg child moves to the center of the merry-go-round, what is the new angular velocity in revolutions per minute? Ignore friction, and assume that the merry-go-round can be treated as a solid disk and the children as...
Three children are riding on the edge of a merry-go-round that is 105 kg, has a 1.40-m radius, and is spinning at 24.0 rpm. The children nave masses of 22.0, 28.0, and 33.0 kg. If the child who has a mass of 28.0 kg moves to the center of the merry-go-round, what is the new angular velocity in rpm? Ignore friction, and assume that the merry-go-round can be treated as a solid disk and the children as points.
