Question
A body starts from rest and accelerates non-uniformly. Its velocity-time graph is a ___.
- Straight line parallel to the time-axis
- Straight line passing through the origin
- Curved line
- Curved line passing through the origin
Hint:
Option d is correct for this graph.
The correct answer is: Curved line passing through the origin
As the body is starting from rest graph will begin from origin and as it is accelerating slope will be positive. For a non-uniformly accelerating motion starting from rest graph will be a curved line passing through origin.
