    The answer for the following question is explained below.

    • Therefore the work done is 130 kilo Joules.

    Explanation:

    Work:

    A force causing the movement or displacement of an object.

    Given:

    mass of the person (m) = 65 kg

    height of the cliff (h) = 2000 m

    To calculate:

    work done (W)

    We know;

    According to the formula:

      W = m × g × h

    Where;

    m represents mass of the person

    g represents the acceleration due to gravity

    where the value of g is;

      g = 10 m/ s²

    h represents the height of the cliff

    From the above formula;

      W = 65 × 10 × 2000

     W = 130,000 J

      W = 130 Kilo Joules

    Therefore the work done is 130 kilo Joules.
