Question

The velocity $-$ time graph of a body moving along a straight line is as follows: The displacement of the body in $5s$ is

• A. $2m$
• B. $4m$
• C. $5m$
• D. $3m$

Answer 1

The correct option is D $3m$

Displacement $=$ Summation of all the area with sign

Displacement is area under $v-t$ graph

$=\frac{1}{2}\times 3\times 2-\frac{1}{2}\times 2\times 1+1\times 1$

$=3m$

Final answer : (d)
