    41.4 m/s

    Explanation:

    Consider downward direction of motion as negative

    v₀ = initial velocity of the package as it is dropped over the side = 12 m/s

    v = final velocity of the package just before it hits the ground

    y = vertical displacement of the package = - 80 m

    a = acceleration = - 9.8 m/s²

    Using the kinematics equation

    v² = v₀² + 2 a y

    v² = 12² + 2 ( - 9.8) ( - 80)

    v² = 144 + 1568

    v = - 41.4 m/s

    The negative sign indicates the downward direction of motion.

    Hence the speed of package comes out to be 41.4 m/s
