Projectile Motion - Initial Velocity with Wind

  1. Sep 27, 2009 #1
    Hey Physics Forums. This is my first post here, and I'm just wondering about how to find what the initial velocity SHOULD be based on all the other information that I provide (it's for a program application I coded).

    Anyways, I have this right now (which is for no wind/0 wind):

    I am just wondering how I would go about factoring in the "wind" and wind's angle.

    Wind Angles:

    ^ 90
    < 180 > 0
    \/ 270

    As you can see, the wind angle starts at 0 and moves counter-clockwise.

    Anyways, here's the formula:

    Velocity = Sqrt((Mass * (DifferenceInX^ 2)) / (2 * (DifferenceInX) * Sin(Theta* PI / 180) * Cos(Thtea * PI / 180) - (2 * (DifferenceInY)) * ((Cos(Theta* PI / 180) ^ 2))))

    Where Theta is the angle of the shot; Difference in X is the difference in coordinates X of the starting position and where you want the shot to end; and DifferenceInY is the difference in coordinates Y of the starting and ending position.

    Please help me out, thanks.
