    Answer:

    44.1m/s

    Explanation:

    Ah, objects in freefall!

    We know that the inital velocity is 0, as it was being held from a skyscraper at time zero.

    We also know that objects accelerate at uniform fashion at 9.8m/s

    Since it did so for 4.5s, multiply them:

    9.8m/s(4.5s) = 44.1m/s

    That would be its final velocity as the initial was zero
