A disk-shaped merry-go-round of radius 2.43 {\rm m} andmass 185 {\rm kg} rotates freely with anangular speed of0.701 {\rm rev/s}.A 60.4 {\rm kg} person runningtangential to the rim of the merry-go-roundat 3.41 {\rm m/s} jumps onto its rimand holds on. Before jumping on the merry-go-round, the person wasmoving in the same direction as the merry-go-round's rim.What is finalangular speed of merry go round?
