1. The radius of the moon is roughly 1080 miles. The acceleration of the gravity at the surface of the moon is about 0.165g, where g is the acceleration of the gravity at the surface of the Earth. Determine the velocity of escape for the moon.

2. Are you aware that $v_e=\sqrt{\frac{2GM}{r}}=\sqrt{2gr}$?
