The physics
Acceleration is the rate of change of velocity — how many metres per second of speed an object gains (or loses) each second. A car doing 0–100 km/h in 6 seconds averages about 4.6 m/s², roughly half a g.
Acceleration of a car from 0 to 100 km/h in 8 s
Answer: acceleration = 3.472 m/s² (in g-force 0.354 g).
What we know
- Initial velocity: 0 m/s
- Final velocity: 100 km/h = 27.77777778 m/s (converted to the unit the formula takes)
- Time: 8 s
Step by step
- Given
- v₀ = 0 m/s, v₁ = 27.77777778 m/s, t = 8 s
- Formula
- a = (v₁ − v₀) / t
- Substitute
- a = (27.77777778 − 0) / 8
- Result
- a = 3.472 m/s²
All results
| Acceleration | 3.472 m/s² |
