A cyclist speeding up from 5 m/s to 10 m/s in 4 s

Answer: acceleration = 1.25 m/s² (in g-force 0.127 g).

What we know

  • Initial velocity: 5 m/s
  • Final velocity: 10 m/s
  • Time: 4 s

Step by step

Given
v₀ = 5 m/s, v₁ = 10 m/s, t = 4 s
Formula
a = (v₁ − v₀) / t
Substitute
a = (10 − 5) / 4
Result
a = 1.25 m/s²

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.
