Question

The velocity-time graph of a body travelling along a straight line is given below. The distance travelled and displacement of the body are respectively -

• A. $6\text{m},0$
• B. $6\text{m},3\text{m}$
• C. $6\text{m},-3\text{m}$
• D. $0,0$

Answer 1

The correct option is A $6\text{m},0$


Distance travelled $=\frac{1}{2}\times 1\times (4+2)+\frac{1}{2}\times 3\times 2=6\text{m}$

Displacement travelled $=\frac{1}{2}\times 1\times (4+2)-\frac{1}{2}\times 3\times 2=0\text{m}$

Hence, option $\left(A\right)$ is the correct answer.
