A 14 0 kg solid homogeneous disk of radius 0 600 m is rotating with an initial angular speed of 50 0 rad s about a frictionless horizontal shaft A 6 00 kg solid homogeneous disk of radius 0 400 m is initially at rest on the same shaft The disks are pushed into contact as shown Because of surface friction the two disks eventually attain a final common angular speed w a Find the final common angular speed wf of the system b In the collision of the two disks kinetic energy is not conserved because nonconservative frictional internal forces act during the contact How much energy was lost to friction in the collision rad wo 50 0 W1 S 0 Go o Before contact After contact rad
