Question:

Disk B has an angular velocity ω0 when it is brought into contact with disk A, which is at rest. Show that

(a) The final angular velocities of the disks are independent of the coefficient of friction μk between the disks as long as μk ?? 0,

(b) The final angular velocity of disk B depends only upon ω0 and the ratio of the masses mA and mB of the two disks.
