A bucket is filled with sand so that the total mass (sand and bucket) is 20 kgs. The bucket is to be lifted to the top of a 20 meter tall building by a rope of negligible weight. However, the bucket has a hole in it, and leaks 0.2 kgs of sand each meter it is lifted. Find the work done lifting the bucket to the top of the building. Joules
