Help With Kinematics/Work, Energy, Power Problem

Homework Statement

Calculate the velocity a 1.0g raindrop would reach if it fell from a height of 1.0km. You may ignore all forces of friction.

Homework Equations

Fg = mg, where g = 9.81 m/s^2
W = Fparallel x d

The Attempt at a Solution

I used Fg = mg to find that Fg = 0.00981 N.
Then, I had no clue what formula to use after this :S.

Thanks.

There's a connection between:

you're starting and ending velocity
and
your acceleration

hint: assume the drop starts from rest... so you know the starting velocity. And the acceleration is also a known constant.
