Solve (problem) if a 40-lb block is suspended from the cord at A, rather than applying the 40-lb force.
Problem
The spool has a weight of 30 lb and a radius of gyration k0 = 0.65 ft. If a force of 40 lb is applied to the cord at A, determine the angular velocity of the spool in t = 3 s starting from rest. Neglect the mass of the pulley and cord
