How much thermal energy is produced

Reference no: EM13682536

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?

E = ____________J

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

v = ____________m/s

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

|F| = ___________N

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

W = _____________J
