Compute horizontal range and maximum height from launch speed and angle with R = v²sin(2θ)/g and H = v²sin²θ/(2g).
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Range | R = v²·sin(2θ) / g (same level) | Galileo parabolic motion 1638 |
| Max range | R_max = v²/g at θ=45° | neglect air resistance |
