Chain and Work

  1. Nov 14, 2009 #1
    1. The problem statement, all variables and given/known data

    A (uniform) chain with a mass of 4.7 kg and a length of 2.0 m lies on a table with 0.7 m hanging over the edge. How much energy is required to get all of the chain back on the table?

    2. Relevant equations

    W= integral(sumF)dx

    3. The attempt at a solution

    NO idea where to start.

    How much work is required to pull the center of mass of the overhanging 0.7 m over the edge of the table?
