Question Details:

The 6 lb disk A has a radius rA= 3" and an initial angular velocity ω0= 375 rpm clockwise. The 15 lbs disk B has a radius of rB=5" and is at rest. A force P of magnitude 2.5 lbs 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
