## Homework Statement

The angular momentum per unit mass of an object orbiting the Sun is given by [tex]h =

na^2 \sqrt{1 - e^2}[/tex], where [tex]n[/tex] , [tex]a[/tex] and [tex]e[/tex] are the mean motion, semi-major axis and eccentricity of the object, respectively. Use [tex]h[/tex] to obtain an expression for the angular velocity of the object as a function of the true anomaly, [tex]f[/tex].

## The Attempt at a Solution

Literally the only formulas involving f that we have in our notes are...

[tex]\.{r} = \frac{na}{\sqrt{1-e^2}}\sin(f)[/tex]

and

[tex]r = \frac{a(1-e^2)}{1 + e \cos(f)}[/tex]

and since I seem to think [tex]\.{r}[/tex] is the angular velocity is the first equation there just the answer?!?
