    Answer

    Radius is 421 m.

    Explanation

    A car with a mass of 1,500 kg requires a centripetal force of 640 N to safely follow a circular curve in the road at 13.4 m/s. Therefore, for radius we use formula which is Fc = mv ^ 2 / r,

    As mass = m = 1500kg,

    Centripetal force = Fc = 640N,

    Velocity = v = 13.4 m / s

    By putting values, Fc = mv ^ 2 / r,

    r = mv ^ 2 / Fc,

    => r = (1500kg). (13.4 m / s) ^ 2 / 640,

    => r = (1500kg). (179.56) / 640,

    r = 269340 / 640,

    => r = 420.84 m.

    Radius is 421 m.
