    Answer:

    Δx = 1.2 m

    Explanation:

    The CHANGE of spring length) (Δx) can be found using PS = ½kΔx²

    Δx = √(2PS/k) = √(2(450)/650) = 1.17669… ≈ 1.2 m

    The actual length of the spring is unknown as it varies with material type, construction method, extension or compression, and other variables we have no clue about.
