Question

The velocity $v$ versus $t$ graph of a body in a straight line is as shown in Fig. The displacement of the body in five seconds is

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

Answer 1

Answer: (B)

$3m$

"Area under the velocity-Time graph gives the Displacement ."

we divide the area into $3$ parts

$A=A_{0-3}+A_{3-4}+A_{4-5}$

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

$A=3m$
