Question
Figure given shows the distance –time graph of the motion of a car. It follows from the graph that the car is
- At rest
- In uniform motion
- In non-uniform acceleration
- Uniformly accelerated
The correct answer is: Uniformly accelerated
Since 
which is in form 
Thus the motion is uniformly accelerated
