sorry didnt completely give question
A car enters a horizontal, curved roadbed of radius 50 m. The coefficient of static friction between the tires and the roadbed is 0.20. What is the maximum speed with which the car can safely negotiate the unbanked curve?

    for safe turn
    Ffriction must be equal to centripetal force
    Fnet= ma
    Ffriction=mv^2/r
    kmg=mv^2/r
    k= v^2/gr unless you give v you cant find coefficient of friction..
    if you give me v I will give you answer
