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 has a mass of 105 kg and a radius of 1.60m. The merry-go-round is spinning at 16.0 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?

A merry-go-round is rotating about its axis by 20.0rpm when a student with mass of 75.0 kg is at 1.0 m from the center. He starts moving toward the edge. Find angular velocity of total system when student is on the edge of merry-go-round. Merry-go-round has mass of 100 kg and radius of 3.0m and moment of inertia of disk is l= 1/2 MR2. Moment of inertia of boy is mR2. (use conservation of angular momentum)

Alex and Riley are two kids standing on a merry-go-round. Alex has half the mass of Riley and is standing at the very edge of the merry-go-round. Riley is standing halfway between the edge and the center of the merry-go-round. The merry-go-round is turning at a constant rate. Which of the following are true? (Select all that apply.) Alex has the larger moment of inertia on the merry-go-round. Riley has the greater angular velocity. Alex has the larger tangential...

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.

(7%) Problem 13: Three children are riding on the edge of a merry-go-round that is a disk of mass 92 kg, radius 1.6 m, and is spinning at 21 rpm. The children have masses of 22.4 kg, 29.6 kg, and 32.6 kg. Randomized Variables M= 92 kg m1 = 22.4 kg m2 = 29.6 kg m3 = 32.6 kg r= 1.6 m f=21 rpm If the child who has a mass of 29.6 kg moves to the center of the...

A merry-go-round, which may be approximated as a solid disk of
mass 90.0 kg and radius 2.00 m, is originally at rest but free to
rotate in the horizontal plane about its center. A child applies an
external force of 20.0 N tangentially to the outer edge of the
merry-go-round, for a duration of 15.0 s.
(a) What is the final angular velocity of the merry-go-round?
(b) What is the average power supplied by the child in the
process?
(c)...

Three children are riding on
the edge of a merry-go-round that has a disk of mass 102 g, radius
1.9 m, and is spinning at 16 rpm. The children have masses of 23.2
kg, 26.4 kg, and 33.4 kg. If the child who has a mass of 26.4 kg
moves to the center of the merry-go-round, what is the new
magnitude of angular velocity in rpm?
