A cockroach of mass m lies on the rim of a uniform disk of mass 4m that can freely rotate about its center like a merry-go-round. Initially the cockroach and disk rotate together with an angular velocity of 0.260 rad/s. Then the cockroach walks halfway to the center of the disk.

a. What is the new angular velocity of the cockroach-disk system?

b. What is the ratio K/K0 of the new kinetic energy of the system to its initial kinetic energy?

c. What accounts for the change in the kinetic energy?

A uniform disk of radius 0.529 m and unknown mass is constrained to rotate about a perpendicular axis through its center. A ring with same mass as the disk\'s is attached around the disk\'s rim. A tangential force of 0.223 N applied at the rim causes an angular acceleration of 0.103 rad/s2. Find the mass of the disk.
