It takes 2.5 s for a small ball released from rest from a tall building to reach the ground. The mass of the ball is 0.05 kg. Calculate the height from which the ball is released.
Ok so I have the time, initial velocity, and the acceleration. But the mass totally throws me off...what would the formula for this problem be?

Never mind! The mass has nothing do with the problem. I got it. :)
