I have a problem involving the rotational version of Newton's Second Law. A spool is resting on a tabletop. A wire is wound around it counterclockwise and the free end of the wire goes over a pulley (located to the right of the spool) at the end of the table and attaches to a hanging mass. What happens to the spool when the system is released? Assume that there is friction between the spool and the table, and the spool undergoes pure rolling motion. Does the spool roll away from/roll toward the pulley? If so, what happens to the hanging mass? Will it be at rest? or moving down, or moving up? If so, what is the reasoning behind it. Thanks.
