A merry go round on a frictionless axle is spinning at 35 rpm. (assume the merry go round is a disk with a radius of 1 meter and mass of 130 kg.) A 40 kg child jumps on it at 0.9m from the center, find the speed of the child on the merry go round.

Three children are riding on the edge of a merry-go-round that is 105 kg, has a 1.60-m radius, and is spinning at 22.0 rpm. The children have 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.

)A 3.5-m diameter merry-go-round with a mass of 275 kg is spinning at 22 rpm. John runs around the merry-go-round at 5.0 m/s in the opposite direction that the merry-go-round is turning, and jumps onto the outer edge. John’s mass is 30 kgAfter John jumps on, a torque is applied that eventually slows down the merry-go-round. If the merry-go-round comes to a stop 15.6 seconds after the torque is applied, what is the magnitude of the torque?

Two children, Angelica (mass 25 kg) and Boris (mass 50 kg), are playing on a merry-go-round (which you can assume is a solid disk with mass 225 kg and radius 1.5m). Assume that any friction on the axle of the merry-go-round is negligible. Part A: Angelica starts spinning the merry-go-round, giving it an angular velocity of 8 rad/s, then she stops pushing it. Boris runs with a speed of 6 m/s directly toward the center of the merry-go-round. He jumps...

A merry-go-round is a common piece of playground equipment. A 3.0-m-diameter merry-go-round, which can be modeled as a disk with a mass of 300 kg , is spinning at 24 rpm. John runs tangent to the merry-go-round at 4.6 m/s, in the same direction that it is turning, and jumps onto the outer edge. John's mass is 30 kg.

On a playground, a merry-go-round with a total mass of 100 kg and a radius of 2.5mis rotating counterclockwise around its center with an angular speed of 0.5 rad/s. A girl with a mass of 40 kgruns at a speed of 4 m/s towards the edge of the merry-go-round and jumps on, as shown. What is the angularvelocity (magnitude and direction) of the merry-go-round after the girl lands on it? Assume the merry-go-roundis a uniform disk and treat the girl...
