Question

The displacement versus time graph of a moving body is given below.

Which one of the following graphs would represent the velocity versus time graph of the moving body?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

We know that the slope of the s-t graph gives the velocity and slope of the v-t graph gives us acceleration.


Hence, For 0 to 6 seconds:
Velocity = Slope = 0 $m{s}^{-1}$
For 6 to 8 seconds:
Velocity = Slope = (2 - 6)/2 = -2 $m{s}^{-1}$
For 8 to 12 seconds:
Velocity = Slope = 0 $m{s}^{-1}$
For 8 to 12 seconds:
Velocity = Slope = (10 - 2)/4 = 2 $m{s}^{-1}$
