Suppose that a merry-go-round, which can be approximated as a disk, has no one on it, but it is rotating about a central vertical axis at 0.2 revolutions per second. if a 100kg man quickly sits down on the edge of it, what will be its new speed? (a disk has a moment of inertia i=(1/2)mr2 , mass of merry-go-round = 200kg , radius of merry-goround=6m)
