A kid of mass 30 kg is initially at the center of a merry-go-round, which we can model as a uniform disk. The mass of the merry-go-round is 150 kg and it has a radius of 2.0 m. The merry-go-round initially has an angular speed of 20 rev/min. The kid begins to crawl radially from the center, gets tired, and stops at 0.33 m from the edge. What is the angular speed of the merry-go-round now in rev/min?
