Answer 2

Escape velocity is calculated using the formula:

Your G is a constant (6.67408(31)×10^−11), M (mass) and R (radius) are given in your case.

Putting this in the formula gives 2372.93 meters per second.

This is an approximation because the moon is not a perfect sphere nor is it of homogeneous density so the actual escape velocity will vary from place to place a little.
