    Spring constant is 6.73 N/m

    Explanation:

    For a spring mass system we have

    Mass x Acceleration due to gravity = Spring constant x Elongation

    mg = kl

    Mass, m = 0.454 kg

    Acceleration due to gravity, g = 9.81 m/s²

    Spring constant, k = ?

    Elongation, l = 0.662 m

    Substituting

    0.454 x 9.81 = k x 0.662

    k = 6.73 N/m

    Spring constant is 6.73 N/m
