The 20-kg roll ofpaper has a radius of gyration kA = 120 mm about an axis passing through point A. It is pin supported at both ends by two brackets AB. The roll rests on the floor, for which the coefficient of kinetic friction is μk= 0.2. If a horizontal forceF = 60 N is applied to the end of the paper, determine the initial angular acceleration ofthe roll as the paper unrolls.
