A bucket begins weighing 15 pounds, including the sand it holds. The bucket is to be lifted to the top of a 20 foot tall building by a rope of negligible weight. However, the bucket has a hole in it, and leaks 0.2 pounds of sand each foot it is lifted. Find the work done lifting the bucket to the top of the building.
