A spool of thread consists of a cylinder of radius R1 = 8.0 cm with end caps of radius R2 = 11.6 cm as depicted in the end View shown in the figure below. The mass of the spool, including the thread, is m = 180 g. The spool is placed on a rough, _, horizontal surface so that it rolls without slipping when a force T = 0.480 N acting to the right is applied to the free end of the thread. For the moment of inertia treat the spool as being a solid cylinder of radius R1, as the extended edges are thin and therefore light. s. \\ r R] 'I l .51.. ll .
