Dynamics: need help finding angular acceleration and final angular velocity. Please help.

Course Textbook Chapter Problem
Classical Mechanics Vector Mechanics for Engineers: Dynamics (8th) by Johnston, Beer, Clausen 16 39P
Question Details:
The 12-lb disk A has a radius rA = 6 in. and an initial angular velocity ωo = 750 rpm clockwise.  The 30-lb disk B has a radius rB = 10 in. and is at rest.  A force P of magnitude 5-lb is then applied to bring the disks into contact. Knowing that μk  = 0.25 between the disks and neglecting bearing friction, determine (a) the angular acceleration of each disk, (b) the final angular velocity of each disk.
