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:

$$\sqrt{\frac{F*r} {m} }$$

I simplified to:

$$\sqrt{g*\mu*r}$$

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

Please some help.

What is the problem? If you give us the complete text of the problem we'll be able to help you more. I don't know what they're asking for so I don't know how to help you.
