A jetliner of mass 8.70*104 kg is in level flight when it encounters a downdraft (a downward wind) that lasts for 1.20 s. The vertical component of the jetliner's velocity is 71.5 m/s after the downdraft subsides. What is the downdraft's average force, F, on the jetliner?

    The downdraft's average force is F = 5.18 * 10⁶ N.

    Explanation:

    m = 8.7 * 10⁴ kg

    V = 71.5 m/s

    t = 1.2 s

    F*t = m*V

    F = m*V/t

    F = 5.18 * 10⁶ N
