Need to find the current velocity at distance X, given that V0, Vmax, and Acc are all known variables.

I have a known initial velocity (lets say 30m/s), maximum velocity(100m/s), and acceleration over time(10m/s^2), how do I find the current velocity at distance X?

I know that I could write some code that says "Oh, when V>100, V=100", but how do I express that veolcity cap mathematically?
