The physics
A projectile — a thrown ball, a water jet, a long jumper — follows a parabola because gravity only pulls vertically while horizontal motion continues unchanged.
Range of a golf ball at 70 m/s and 12° (no drag)
Answer: range = 203.23 m (max height 10.8 m, flight time 2.97 s).
What we know
- Launch speed: 70 m/s
- Launch angle: 12°
A real drive goes a different distance: drag and spin lift matter at this speed. This is the vacuum answer.
Step by step
- Given
- v₀ = 70 m/s, θ = 12°
- Formula
- R = v₀² · sin(2θ) / g
- Substitute
- R = 70² × sin(2 × 12) / 9.80665
- Result
- R = 203.23 m
All results
| Range | 203.23 m |
|---|---|
| Max height | 10.8 m |
| Flight time | 2.97 s |
