AdamHeard, care to share how you did your calculations? Brushing up wouldn't be a bad idea.

I just used my ti-84 to be honest
I integrated the acceleration of 9.8m/s/s to get a velocity as 9.8(x) m/s.
I then graphed the integral of that (position) and just saw where it intersected a horizontal line that was the distance traveled. That gave the time to travel that distance; From there the speed was as easy as putting that time into the velocity equation above.
It's all really basic calculus. So, if you haven't taken it yet, don't worry; you'll get it really fast once you do.
