NOTE: This is a multi-part question. Once an answer is submitted,you will be unable to return to this part. A drum of 4-in. radius is attached to a disk of 8-in. radius. The disk and drum have a total weight of 12.5 lb and a combined radius of gyration of 6 in. A cord is attached as shown and pulled with a force P of magnitude 5 lb. Know that the disk rolls without sliding. Determine the angular acceleration of the disk and the acceleration of G (You must provide an answer before moving on to the next part.) The angular acceleration of the disk is「rad/s2. The acceleration of G is ft/s.
