Working

  1. 1a = (27.8 − 0) ÷ 6.2 = 4.4839 m/s²

Quick answer

Acceleration is the change in velocity divided by the time taken.

The formula

a = (v − u) ÷ t

Frequently asked questions

What is a fast 0–60?

Under 5 seconds is quick, under 3 is supercar territory — about 0.9 g of sustained acceleration.

Is deceleration negative acceleration?

Yes, mathematically it's the same quantity with the opposite sign.
