Let there be a disk shaped merry-go-round of radius R = 2m and mass M = 90 kg with a
30 kg child riding on at the outer edge. It spins at a rate of 2 revolutions per second with
%3D
the child on it.
a. What is the initial angular velocity?
b. If the child falls off, what is the new angular velocity? (hint use conservation of
angular momentum)
