A 17-kg roll of paper, originally at rest, is supported by bracket All If the roll rests against a wall where the coefficient of kinetic friction is = 0.3, and a constant force of 30 N is applied to the end of the sheet, determine the tension in the bracket as the paper unwraps, and the angular acceleration of the roll. For the calculation, treat the roll as a cylinder.
