An infinitesimally thin rope is held on a frictionless table with one-fourth of its length hanging over the edge. If the rope has length L and total mass m (assuming uniform mass distribution), how much work is required to pull the hanging part back onto the table.
U = mgh
The length of the overhanging piece of string is (L/4) and the mass of this piece is (m/4) so do i just plug in the values, presuming I'm using the right equation... work = mLg/16 ??
