Homework Statement



A cycler is going through the winding, cycling on a circle of radius 6m and is slanting with alpha=75^ to the horizontal surface. What's his velocity?

Homework Equations



[itex]T=\frac{mv^{2}}{R}[/itex]
[itex]Fc=\mu F_{N}[/itex]

The Attempt at a Solution



We have two forces on the cycler - centrifugal force and friction. They are equal (or at least should be? Though I don't know why...) so we have T=Fc and thus [itex]\frac{mv^{2}}{R}=\mu F_{N}[/itex]. How should I use it, though, if I have only 75^ and the radius given?
