How to find a position function of an object as it falls towards to the Earth and the acceleration changes?

with respect to time?





If the acceleration doesn't change and ignoring air resistance then it's Y = -4.9*T²+H where Y is the height, T is time, and H is the initial height. I got that. But if the acceleration changes due to a change in position then I have an equation that loops on itself and makes no sense. I tried to integrate it and it doesn't work. Can you please work it out?

You would improve your chances of getting an answer if you told us what the equation was for how the acceleration changes with position.
