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

A car moving at 5 m/s tries to round a flat corner that has a radius of curvature of 8 m. How large must the coefficient of friction be between the wheels and the roadway if the car is not to skid?

2. Relevant equations

mv^2/r i don't know anything else. Fc=Fn(mk)

3. The attempt at a solution
Don't really know where to start?

Use good ol' Newton's second law …

what must the acceleration be? and what must the forces be, to produce that acceleration?
