The spool has a mass of 75 kg and a radius of gyration k_G = 0.380 m. It rests on the inclined surface for which the coefficient of kinetic friction is μ_k = 0.15. If the spool is released from rest and slips at A, determine the initial tension in the cord and the angular acceleration of the spool.
