Figure below shows a 10 kg homogeneous disk of radius 0.2 m. The disk is at rest before the hori-zontal force P = 60 N is applied to its mass

center G. The coefficients of static and kinetic frictionfor the surfaces in contact are 0.20 and 0.15, respectively. Determine the angular acceleration ofthe disk and the acceleration of G after the force is applied. (20 points)
