Homework Help: Coefficient of friction of a moving car

  1. Jan 26, 2010 #1
    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?

    Start with the frictional force providing the centripetal force.

    Hi katem! Welcome to PF! :smile:

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

    Use good ol' Newton's second law …

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