Question

Map pling learning You are using a pulley system to lift a hanging weight. You arrange the pulleys as shown in the diagram below, and pull down on the end of the rope with a force of 30 N. As you pull, the end of the rope moves a distance of 0.1 m downward On the diagram, drag the appropriate labels to indicate both the amount of work (in joules) that you do while pulling the rope, and the amount of work done by the pulley on the hanging weight, Assume that the pulley itself is massless, and that friction is negligable. 6.030 1.560 300 15 600 3.0 150 0.1 m 30 N work in work out

Explanation / Answer

Since 30N of force is applied to pull the string down by 0.1 m,so, work in is given by:
W(in)= 30*0.1 = 3J
Now, since the total energy of the system is always conserved,so,
W(out) + W(in)= 0 => W(out) = -3J
