    ANYTHING that’s dropped near the Earth’s surface and isn’t affected by air resistance falls 9.8 m/s faster at any time than it did 1 second earlier.

    0.5 second after it was dropped with zero speed, it’s falling at

    (0.5) x (9.8 m/s)  =  4.9 m/s .

    It makes no difference which building it was dropped from.
