3-D Projectile Motion Simulator Aiming Instructions
The speed V and elevation angle q determine the range and the time spent in the air.
Azimuth angle f is the angle measured along the ground. In the simulation (not in the picture above) an azimuth angle of 0o will send the projectile to your right along the screen, and an azimuth angle of 90o will send the projectile "into" the screen.
