First, find the distance you need to travel. The formula for calculating distance travelled with a given constant acceleration rate is this, only without the absolute value bars:



In simple terms, just find the average speed of travel (by adding the old speed with the new speed, the vertical speed) and multiply by the time you spend at this average speed and you have a simple form of acceleration (without drag). It's mainly just the matter of converting between units, mainly quants to feet (or meters), and seconds to ticks (16 ticks make one second).

This'll get you started.
