    Answer:

    W = 14523.6 J

    Explanation:

    Given,

    Mass = 3.9 Kg

    Vertical height , h = 380 m

    Work done against gravitational force

    W = m g h

    g is acceleration due to gravity

    W = 3.9 x 9.8 x 380

    W = 14523.6 J

    Hence, the work done by the gravitational force is equal to W = 14523.6 J
