hello,(adsbygoogle = window.adsbygoogle || []).push({});

find velocity required to keep an object in moon's orbit? so far, a = velocity squared over radius and force equals g constant times mass 1 times mass 2 over radius squared, but the object's mass is not given and mass of moon can be found, any help?
