I can't figure out how to solve for the minimal speed needed if they only provide me a radius. I am using this formula:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] \sqrt{\frac{F*r} {m} } [/tex]

I simplified to:

[tex] \sqrt{g*\mu*r} [/tex]

,but i don't have no idea how to solve for [tex] /mu [/tex].

Please some help.
