1. The problem statement, all variables and given/known data A uniform chain has mass m = 7.51 kg and length L = 8.5 m. It is held on a frictionless table with L/12 hanging over the edge. Find the work needed to pull the hanging part back onto the table. 2. Relevant equations * Must do the energy considerations! Let's see... →½mv² →mgh 3. The attempt at a solution Attempt? ½ * 1/12 * m * v² = mgd?
