The radius of the roll of paper shown in the figure is 7.6 cm and its moment of inertia is I = 2.9 × 10-3 kg·m2. A force of 2.9 N is exerted on the end of the roll for 1.1 s, but the paper does not tear so it begins to unroll. A constant friction torque of 0.11 m·N is exerted on the roll which gradually brings it to a stop. Assume that the paper's thickness is negligible. (a)...
