Hey, I was wondering what equations the following equation is derived from:(adsbygoogle = window.adsbygoogle || []).push({});

v=w√(A^{2}-x^{2})

I figure v=wA is one of them but I'm not sure how A^{2}=A-x

Thanks.

edit: The only reason I don't think this is an equation I have to memorize, but one that I can build from equations I already have memorized.
