    Need your help please. Thanks. Elementary Application of Differential Equations

    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.

    Answer: 1.5 miles/sec
