Spool B is at rest and spool A is rotating at 6 rad/s when the slack in the cord connecting them is taken up. If the cord does not stretch, determine the angular velocity of each spool immediately after the cord is jerked tight. The spools A and B have weights and radii of gyration W_A = 30 lb, k_A = 0.8 ft, W_B = 15 lb, k_B = 0.6 ft, respectively.
