1a. A cockroach of mass m lies on the rim of a uniform
disk of mass 9.00 m that can rotate freely about its
center like a merry-go-round. Initially the cockroach and disk
rotate together with an angular velocity of 0.456 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/K0 of the new kinetic energy of the
system to its...
