    Answer:

    Total length of spring 0.647 m

    Explanation:

    We have given mass of the person m = 150 kg

    Acceleration due to gravity g=9.8m/sec^2

    Spring constant k = 10000 N/m

    Nominal length of spring = 0.50

    According to hook’s law

    mg=kx

    150\times 9.8=10000\times x

    x = 0.147 m

    So total length of spring = 0.50+0.147 = 0.647 m
