30f5 -/1 ;= View Policies Current Attempt in Progress In Figure (0), you pull upward on a rope that is attached to a cylinder on a vertical rod. Because the cylinder ts tightly on the rod, the cylinder slides along the rod with considerable friction. Your force does work (W = + 100 J) on the cylinderrodEarth system (Figure (b)). An "energy statement\" for the system is shown in Figure (c): the kinetic energy K increases by 50 J, and the gravitational potential energy Ug increases by 20 J
