The function gives the speed in feet per second (ft/s) of a free-falling object after it has fallen x feet (ignoring air resistance). FInd the speed of the object after it has fallen 25 feet. If necessary, round your answer to the nearest tenth.

    time t fall 25 ft
    16t^2 = 25
    t^2 = 25/16
    t = 5/4 seconds

    v = 32t
    so after 5/4 seconds, v = 32(5/4) = 40
    the object is falling at 40 ft/sec
