    Answer:

    h = 20 m

    Explanation:

    Given that,

    Force to lift a firefighter’s equipment, F = 270 N

    Work done, W = 5400 J

    We need to find the height climbed by the firefighter. We know that,

    Work done, W = Fd

    So,

    d=\dfrac{W}{F}\\\\d=\dfrac{5400}{270}\\\\d=20\ m

    So, the firefighter climb from a height of 20 m.
