The spool has a weight of 140 lb and a radius of gyration of 2.1 ft. The cord is wrapped around the inner core and the end is pulled with a force P of 35 lb. Find the angular velocity of the spool after the center O has moved 8 ft to the right if the spool starts from rest. Assume it does not slip and neglect the cord mass. Given: Find: Assume: Equations: Soln: 3 ft- A 2 ft
