(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 Tis applied at an angle 0 to a cord securely wrapped around the inner radius as rO TI G shown. If T = 50 N, 0 = 30°, and friction coefficients with the ground surface u, = 0.10 and uk = 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.
