    3.92 cm

    Explanation:

    k = spring constant of the spring scale = 1500 N/m

    m = mass of the brick = 3 kg

    x = stretch caused in the spring

    h = height dropped by the brick = x

    Using conservation of energy

    Spring potential energy gained by the spring scale = Potential energy lost

    (0.5) k x² = mgh

    (0.5) k x² = mgx

    (0.5) k x = mg

    (0.5) (1500) x = (3) (9.8)

    x = 0.0392 m

    x = 3.92 cm
