Question

A car has an acceleration of 1m/s².What is the change in its velocity after every 3 seconds?

Answer 1

A car has an acceleration of 1m/s², it means that the velocity of the car increases by 1m/s every second. So after every three seconds the car's velocity will have increased by 3 m/s.

$1m/s^2 × 3s = 3m/s$
