Homework Statement


[/B]

As stated in the included pics, you are climbing up a massless rope on a frictionless pulley, attached to a block equal to your mass which is hanging on the other side. You move a distance d along the rope. Does the block move? If so, how much?

The first one is now readable. The 2nd one still not. I'm an old guy. Maybe some of our younger members will be able to. Also, you REALLY shouldn't post chicken-scratch handwritten solutions. Typed-in work is the order of the day here.

My problem is not the readability but the lack of explanation.
No definition of variables, no text to explain the starting equations in terms of elementary principles or how equations are combined, and the tabular layout robs it of clues as to the logical flow.
