a truck traveling along a straight road at 20km/h,increases its speed to 120km/hr in 15 s. If its acceleration is constant. determine the distance traveled.

  • dynamics -

    20km/h = 20000m/3600s = 5.56 m/s.
    120km/h = 120000m/3600s = 33.33 m/s.

    a = (V-Vo)/t = (33.33-5.56) / 15 = 1.85 m/s^2.

    d = Vo*t + 0.5a*t^2.
    d = 5.56*15 + 0.925*15^2 = 292 m.
