    A disk of mass M and radius R unwinds from a tape wrapped around it. The tape passes over a frictionless pulley, and a mass m is suspended from the other end. Assume that the disk drops vertically.

    a) Relate the accelerations of m and the disk, a and A, respectively to the angular acceration of the disk.

    Ans clue- If A were to equal 2a, then angular acceleration would equal 3A/R

    b) Find a, A and angular acceleration
