Homework Statement
A uniform rope of length L and mass M is held on a frictionless table by a force
F. One fourth of its length (¼L) is hanging over the edge. Find the work required
to pull the hanging part back onto the table.
Homework Equations
W=Fd
The Attempt at a Solution
I have no idea how to solve it, but what I've written down is mass per unit length is lambda=M/L and the part on the table has length .75L. The part hanging off weighs (lambda).25L and the part on the table weighs (lambda).75L. I'm not really sure where to go from here.
