    f = ma

    a = 6350/2600 = 2.44 m/s²

    v = v₀ + at

    v = 29 + (–2.44)(1.6) = 25.1 m/s

    Equations of motion (straight line, constant acc)

    d = ½at² + v₀t + d₀

        d is displacenemt

        v₀ is initial velocity

        d₀ is initial position

    v = v₀ + at

    v² = v₀² + 2ad
