Coefficient of friction of a moving car

[katem]

Homework Statement

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?

Homework Equations

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

The Attempt at a Solution

Don't really know where to start?

(try using the X² and X₂ tags just above the Reply box )

Use good ol' Newton's second law …

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