Homework Answers
ω = v/r
since ω is constant, tangential velocity v will be doubled when radius is doubled to keep the ω constant.
Hence the tangential velocity will increase by a factor of 2.

A disk-shaped merry-go-round of radius 2.63 m and mass 155 kg rotates freely with an angular speed of 0.673 rev/s. A 59.4 kg person running tangential to the rim of the merry-go-round at 3.17 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. (a) Does the kinetic energy of the system increase, decrease, or stay the same when the person jumps on the merry-go-round?...
