A uniform disk, with mass M = 2.5 kg and radius R = 20 cm is mounted on a fixed horizontal axle. A block with massm = 1.2 kg hangs from a massless cord that is wrapped around the rim of the disk. If the cord does not slip and there is no friction at the axle, find(a) the acceleration of the falling block(b) the angular acceleration of the disk(c) the tension in the cord
