What is the maximum speed with which a 1150-kg car can round a turn of radius 71 m on a flat road if the coefficient of static friction between tires and road is 0.80?

May someone walk me through this problem step by step? Thank you

*The equation friction coefficient= v^2/Rg does not make any sense. Because, I do not have a velocity.

  1. mv²/R= F(fr)
    F(fr)=μN=μmg
    mv²/R= μmg
    μ= v²/Rg
    Follow up
    v= sqrt(μ•R•g) =
    =sqrt(0.8•71•9.8) =23.6 m/s

    A 850-kg race car can drive around an unbanked turn at a maximum speed of 61 m/s without slipping. The turn has a radius of 160 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 11000 N

    friction between tires and pavement supplies the centripetal acceleration necessary for a car to turn. Using the coefficients of friction for rubber on concrete calculate the maximum speed at which a car can round a turn of radius
