Question
A disk-shaped merry-go-round of radius 2.63 m and mass
155 kg rotates freely with an angular speed of 0.641 rev>s. A
59.4-kg person running tangential to the rim of the merry-go-round
at 3.41 m>s 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. What is the final angular speed of the
merry-go-round?
