    Use kinematic equation:

    vf² = vo² + 2g (xf - xo)

    vf = final velocity = 10 m/s

    vo = initial velocity = 0 m/s (i. e. at rest)

    g = 9.81 m/s²

    xf - xo = distance traveled = d

    *rearrange equation to solve for d

    (vf² - vo²) / (2g) = d

    d = ((10 m/s) ² - (0 m/s) ²) / (2*9.81 m/s²)

    d = (100 m²/s²) / (2*9.81 m/s²)

    d = 5.097 m
