# Homework Help: Cycler on a winding and velocity

1. The problem statement, all variables and given/known data

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?

2. Relevant equations

$T=\frac{mv^{2}}{R}$
$Fc=\mu F_{N}$

3. 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 $\frac{mv^{2}}{R}=\mu F_{N}$. How should I use it, though, if I have only 75^ and the radius given?

Does this look right?
