  1. Oct 31, 2012 #1
    1. The problem statement, all variables and given/known data
    The gravitational acceleration of the moon is 1.6 m/s^-2. Estimate its escape velocity and explain how you did this?

    2. Relevant equations

    v= square roots(2GM/r)

    3. The attempt at a solution
    I have absolutely no idea how to do this question at all
