A cockroach of mass m lies on the rim of a uniform disk of mass 6.00*m that can rotate freely about its center. Initially the cockroach and disk rotate together with an angular velocity of 0.362 rad/s. The the cockroach walks halfway to the center of the disk.

(a) what then is the angular velocity of the cockroach-disk system?

(b) What is the ratio of the new kinetic energy of the system to its initial kinetic energy?

Explanation:

Go there!

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
