Proper Length

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.

An object is released from rest at a height of h. During the final second of its fall, it traverses a distance of 38m. Determine h. I would like to know the solution but also maybe an explanation on how I would know what process to take. For the last second, I was able to find that final vf = 38m/s. That is vf = deltax/deltat, or 38m/1s. I plugged it in to vf2 = vo2 + 2a(deltax), since I think that vf shouldn't change for h, but I got the wrong answer. Please explain.
