Find the velocity (in m/s) of a freefalling object released from rest after it has fallen 100m. I don't understand the formulas to use or anything. please help.

physics please help!  Quidditch, Wednesday, September 17, 2008 at 12:17am
A handy equation for an object with 0 initial velocity and constant acceleration is:
v^2 = (2*a*s)
where
v = final velocity
a = acceleration (in this problem it is gravity)
s = distance
