    Answer:

    d=1/2 (a)(t^2)

    D = distance

    A = acceleration

    T = time

    acceleration due to gravity is 32 ft/second

    so, d=1/2 (32)(5^2)

    d=16(25)

    d=400

    Answer:

    400 ft.

    Explanation:

    D= 1/2 gt^2

    =1/2(-32 ft/sec^2)(5 sec^2)

    = -(1/2)(32)(25) ft

    D= -400 ft, down
