A meteorite has a speed of 75.0m/s when 800km above the Earth. It is falling vertically (ignore air resistance) and strikes a bed of sand in which it is brought to rest in 3.50m.

1. How much thermal energy is produced?

2. What is its speed just before striking the sand?

3. What is the average force exerted by the sand on the meteorite?

4. How much work does the sand do to stop the meteorite (575kg)?
