Problem 19.55 Disk A initially has a counterclockwise
angular velocity 0=50 rad/s. Disks B and C are
initially stationary. At t =0, disk A is moved into contact
with disk B. Determine the angular velocities of
the three disks when they have stopped slipping relative
to each other. The masses of the disks are mA =
4 kg,mB =16 kg, and mC =9 kg.
