A leaky 8 lb bucket is lifted from the ground into the air by pulling in 20 ft of rope at a constant speed. The rope weighs 0.09 lb/ft. The bucket starts with 3 gal of water (24 lb) and leaks at a constant rate. It finishes draining just as it reaches the top. How much work is spent raising the bucket, water and rope?

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
