A disk-shaped merry-go-round of radius 2.83 and mass 185 rotates freely with an angular speed of 0.611 . A 56.4 person running tangential to the rim of the merry-go-round at 3.01 jumps onto its rim and holds on. Before jumping on the merry-go-round, the person was moving in the same direction as the merry-go-round’s rim.
