    The equation: Vf = Vi + at should answer this question, where:

    Vf = Unknown

    Vi = 0

    a = acceleration = 9.8 m/s^2

    t = 6 seconds

    Plug values in:

    Vf = 0 + 9.8*6

    Vf = 58.8 m/s

    I noticed that this is not on your list of answers, which means that some value from your problem is incorrect. I would double check that.
