Calculate escape velocity, cancelling the m would result from setting it equal to 1/2*mv^2, now v = sqr(GM/r), and the orbit needs to be less than this. interesting stuff...

hello, 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?
