According to a local scientist, a typical rain cloud at an altitude of 2 m will contain, on average, 3×107 kg of water vapour. Determine how many hours it would take a 2.5 kW pump to raise the same amount of water from the Earth’s surface to the cloud’s position.

A bucket begins holding 10 kgs of sand. The bucket is to be lifted to the top of a 15 meter tall building by a rope with density 0.4 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.
