## Homework Statement

Show that the angular momentum in circular orbit around a mass

M can be written as functions of just the masses, the

orbit radius, and G.

## Homework Equations

L = r x p = r x mv

L = Iw

## The Attempt at a Solution

I had no trouble showing that the total energy can be written with these variables, but the angular momentum is proving much tougher. I know this has to do with Keplars Law and maybe this will help:

Newton's law of universal gravitation states that the force is proportional to the inverse square of the distance; a_r = -GM/r^2
