Question

# The figure below shows the velocity-time graph of a moving car. It has four sections A, B, C, and D. Arrange these sections in the graph in the ascending order of the accelerations of the car.

- A < B < C < D
- D < C < B < A
- C < A < B < D
- B < A < C < D

Hint:

### Steeper the slope greater the velocity.

## The correct answer is: C < A < B < D

### In position-time graph, slope represents the velocity of body. Hence, steeper the slope greater the velocity. Or velocity can also be determined by using formula Speed = distance/time. And respectively compare the velocity of each particle we get answer as C<A<B<D.
