A drum of 100-mm radius is attached to a disk of 200-mm radius. The disk and drum have a combined mass of 5 kg and a combined radius of gyration of 150 mm. A cord is attached to the drum at A and pulled with a constant force P of magnitude 25 N. Knowing that the disk rolls without sliding and that its initial angular velocity is 10 rad/s clockwise, determine

(a) The angular velocity of the disk after 5 s,

(b) The corresponding total impulse of the friction force exerted on the disk at B.
