Question
A car moves at a speed of 5 m/s throughout its journey. What is its acceleration?
- 5 m/s2
- 0 m/s2
- 2 m/s2
- 3 m/s2
Hint:
Acceleration is rate of change of velocity.
The correct answer is: 0 m/s2
As a car moves with the same speed throughout its journey then there will be no change in velocity hence the acceleration will be zero.
the car is not speeding up or slowing down.
