I didn't know where to put this thread...but here it goes.. I want to get the XYZ components of a initial velocity...i know that there should be a mathematical way to do it...for example, i have a initial velocity of 52.3 meters/second and knowing things like pitch and heading angles, there should be a way to determine or calculate the velocity components in XYZ axis...
