Applied Newtons Law

  1. Oct 1, 2005 #1
    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:

    [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.

    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.
