Compute the roational kinetic energy

Reference no: EM13309927

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

(d) the angle turned after 6.0s, and

(e) the roational kinetic energy.
