Problem 9  A chain 62 meters long whose mass is 26 kilograms is hanging over the edge of a tall building and does not touch the ground. How much work is required to lift the top 14 meters of the chain to the top of the building? Use that the acceleration due to gravity is 9.8 meters per second squared. Hint: Don't forget that when you lift the top 14 meters of the cable you are also lifting the bottom 48 meters of the cable, just not all the way to the top.
