Problem - 16P48 A particular merry-go-round has the form of a disk of mass . / and radius R, sup- ported frictionlessly at its center. A person of mass m is standing at the rim, and the entire system is rotating at angular velocity wo. If the person starts to walk around the rim at speed do relative to the merry-go-round rim, in the same direction in which the rim is rotating relative to the ground, what is the new angular velocity my of the merry-go-round
