How much work is done by the Moon's gravitational field as a 1100kg meteor comes in from outer space and impacts on the Moon's surface?

W=GMm/r

The Attempt at a Solution



W=6.67 X 10^-11(6 X 10^22)(1100kg)/1.5 X 10^6
=2.9 X 10^9

Thank you very much

You should be getting the correct answer as long as the numbers you're using are correct. Check that value for the radius of the moon. Shouldn't it be 1.7*10^6 m? If so, your answer may be off a little bit.
