A uniform disk of mass M=12.0 kg and radius R=.75 m is free to rotate about a frictionless axle through its center. A cord is wrapped around the rim of the disk and is pulled with a stead tension of T=100N. As the cord is unwound, the disk rotates and we assume that there is no slippage between the cord and the rim of the disk. I the disk starts from rest, find the

(a) the angular acceleration

(b) angular velocity

(c) the tangential velocity of the disk

(d) the angle turned after 6.0s, and

(e) the roational kinetic energy.
