A disk of uniform mass M and radius R (Icm = 1 / 2MR2) is tied to a rope that in turn is tied to the ceiling, as shown in figure 2. The mass is released from rest and its center of mass low with a constant acceleration of (Assume that there is friction between the string and the disc and therefore it does not slip.):
