Joanne drives her car with a mass of 1000 {\rm kg} at a speed of 23m/s .

Find a road friction force that is need to bring her car to a halt in 14s .

  • Physics -

    V = Vo + a*t.
    a = (V-Vo)/t = (0-23)/14 = -1.64 m/s^2.

    F = m*a = 1000*(-1.64) = -1640 N.

    The negative sign means that the force
    is opposing vehicle movement.
