A bucket begins holding 15 kgs of sand. The bucket is to be lifted to the top of a 20 meter tall building by a rope with density 0.2 kg/m. 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 and rope to the top of the building. Use 9.8 m/s² for gravity. 3920 x
