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 ball kicked at 25 m/s and 45°
Answer: range = 63.73 m (max height 15.93 m, flight time 3.61 s).
What we know
- Launch speed: 25 m/s
- Launch angle: 45°
No air resistance, launched and landing at the same height.
Step by step
- Given
- v₀ = 25 m/s, θ = 45°
- Formula
- R = v₀² · sin(2θ) / g
- Substitute
- R = 25² × sin(2 × 45) / 9.80665
- Result
- R = 63.73 m
All results
| Range | 63.73 m |
|---|---|
| Max height | 15.93 m |
| Flight time | 3.61 s |
