A 10 ft. pole weighs 30 Ibs. (of force, to be clear). It lies flat on the ground. You lift one end of the pole until it stands vertically, the other end of the pole has been braced to the ground while you lift the other end up. Once the pole is upright, the segment of length Ax at height x has been raised a vertical distance of x feet. How much work is done to raise the pole vertically?
