Physics

A cockroach of mass m lies on the rim of a uniform diskof mass 4.00 m that can rotate freely about its centerlike a merry-go-round. Initially the cockroach and disk rotatetogether with an angular velocity of 0.230 rad/s. Then thecockroach walks half way to the center of the disk.

What then is the angular velocity of the cockroach-disk system?What is the ratio K/K0 of the newkinetic energy of the system to its initial kinetic energy? Whataccounts for the change in the kinetic energy?
