The 22-kg roll of paper has a radius of gyration k = 90 mm about an axis passing through point A. It is pin supported at both ends by two brackets AB. The roll rests against a wall for which the coefficient of kinetic friction is = 0.2 and a vertical force F = 30 N is applied to the end of the paper. (Figure 1) Part A Determine the angular acceleration of the roll as the paper unrolls. Express your answer using three significant figures. Enter positive value if the angular acceleration is clockwise and negative value if the angular acceleration is counterclockwise.
