Problem $16\mathrm{.}041-$ Rotating disks brought to contact

Disk A has a mass of $6\mathrm{.}800$ kg and an initial angular velocity of $360$ rpm clockwise; disk $B$ has a mass of $3\mathrm{.}200$ kg and is initially at rest. The disks are brought together by applying a horizontal force of magnitude $20$ N to the axle of disk $A.$ Assume that ${}_k=0\mathrm{.}15$ between the disks. Neglect bearing friction.

Problem $16\mathrm{.}041.$b $-$ Angular velocity of disks brought to contact

Determine the final angular velocity of each disk.

The angular velocity of disk $A$ is

rpm $.$

The angular velocity of disk $B$ is

$$ rpm $$
