Hi, I'm trying to solve something that I'm very sure is simple, I just can't seem to find the right equation.

A rocket is travelling straight up, with an acceleration of 20m/s^2. I need to know how long it takes to reach a height of 1379.8m (this is the second part of a question).

I am confused about the acceleration. Does the fact that it's travelling at 20m/s mean that after 2 seconds it's travelling at 400 m/s and at 3 seconds it's travelling at 800 m/s?

And to work out the time it takes to travel that far the equation would be t = 1379.8 / ?

Thanks
