A merry-go-round modeled as a disk of mass 100 kg and radius 2.0
m is rotating around a
frictionless vertical axle. After a person of mass 60 kg jumps onto
the merry-go-round, the
system’s angular speed decreases to 2.0 rad/s. If the person walks
slowly from the edge toward
the center, find the change in the system’s rotational kinetic
energy caused by her movement to
0.5 m from the center.
