(Meriam and Kraige 6th ed. 6/89) The spool (ro = 0.2 m, ri = 0.075 m) has a mass of 25 kg and radius of gyration kG = 175 mm. Constant force T is applied at an angle 0 to a cord securely wrapped around the inner radius as %3D T. ro TI G shown. If T = 50 N, 0 = 30°, and friction coefficients with the ground surface us = 0.10 and p = 0.08, find the angular acceleration of the disk, the acceleration of its center of mass G, and the friction force which the surface exerts on the spool. Assume that the spool is initially at rest.
