comment Projectile Motion with Air Resistance and Wind
Also, I have seen this document before, but am unsure of something in it. When they say ax = -(D/m)v*vx, what does v*vx mean exactly?

Wouldn't the wind have an effect on on the object other than just changing the relative speed? The force of the wind acting on the object would change things, would it not? The wind can act in any direction in this scenario. To clarify, if the angle of the wind is between 0 and 90 degrees, or between 270 and 360 degrees, it will be acting in the positive x direction, thus affecting the acceleration in that direction. And the same for the y direction. Also, how would I tie in terminal velocity to this situation, so that the speed increases, then slows down as it approaches terminal velocity?

And I recognize its complexity and the variables involved, as I have been working on combining them into a few unified equations for the past few days, but to no avail. Hence my post on here, where people are undoubtedly more talented at such matters than I. Whatever you can do will be most helpful!

A precision of maybe .01 would be fine for my purposes. Maybe even less, depending on how time-consuming the programming is.
