## Homework Statement

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?

## Homework Equations

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
