Three children are riding on the edge of a merry-go-round that has a mass of 105 kg and a radius of 1.50 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 point masses.
