Question

The velocity-time graph of a particle moving in a straight line is as shown in figure, initial velocity of particle is zero. Find the total displacement of the particle during its journey.

• A. $90\text{m}$
• B. $75\text{m}$
• C. $105\text{m}$
• D. $100\text{m}$

Answer 1

The correct option is B $75\text{m}$

Given, velocity-time graph as below

Displacement of the particle is the area under the velocity-time curve
So, it is given as
$S=\frac{1}{2}\times 6\times 25=75\text{m}$
