A boy with a mass of m=kg stands near the edge of a merry-go-round (MGR) which is not spinning.
The system's (boy + MGR) total moment of inertia about the center is I=kg m^{2}. The
boy standing at r=m from the center of the MGR suddenly jumps off in a tangential
direction with a speed of v=m/s. How fast will the MGR be rotating when the
boy leaves it?
