A ladybug crawls along the radius of a rotating compact disk of mass M = 0.015 kg and radius r = 0.06 m (ldisk = Mr²/2). The pivot is frictionless and the disk is initially rotating with angular speed wa = 31.416 rad/s. The ladybug starts at the outer edge (Figure A) and ends at center (Figure B). At the end of the ladybug's travel the disk rotates with angular speed wg = 31.510 rad/s. WB Figure A Figure B...
