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.
A train going from 0 to 300 km/h in 5 minutes
Answer: acceleration = 0.278 m/s² (in g-force 0.028 g).
What we know
- Initial velocity: 0 m/s
- Final velocity: 300 km/h = 83.33333333 m/s (converted to the unit the formula takes)
- Time: 5 min = 300 s (converted to the unit the formula takes)
Step by step
- Given
- v₀ = 0 m/s, v₁ = 83.33333333 m/s, t = 300 s
- Formula
- a = (v₁ − v₀) / t
- Substitute
- a = (83.33333333 − 0) / 300
- Result
- a = 0.278 m/s²
