Homework Statement
Ok I'm trying to derive [tex]a=v^2/r[/tex]
Homework Equations
The Boas book gives me two equations to start off with:
[tex]r^2=\vec{r}*\vec{r}+constant[/tex]
and
[tex]v^2=\vec{v}*\vec{v}+constant[/tex]
The Attempt at a Solution
Where the hell did those equations come from. I know it gives me the right answer but I don't understand. I can actually do the rest of the derivation easily.
Thanks
As a grad student I am embarressed I don't know this.
