A cockroach of mass /11 lies on the rim of a uniform disk
Chapter 11, Problem 52(choose chapter or problem)
A cockroach of mass /11 lies on the rim of a uniform disk of mass 4.00/11 that can rotate freely about its center like a merrygo-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 then is the angular velocity of the cockroach-disk system? (b) What is the ratio K/Ko of the new kinetic energy of the system to its initial kinetic energy? (c) What accounts for the change in the kinetic energy?
