    Speed & Velocity & Friction Force ???

    1. The problem statement, all variables and given/known data
    With What Max.Speed??? a Car can move in horizontal curve with radius r=25m,
    if the coefficient of friction is u=0,8

    2. Relevant equations

    ƒ = μN S= D/T

    3. The attempt at a solution

    i tryed bunch of garbages so as i dont kno which is right:S

    The frictional force provides the centripetal force.

    So Frictional force=centripetal force.
