Question

In the displacement ($d$) versus time ($t$) graph of given figure, the value of average velocity in the time interval $0$ to $20s$ is (in $m/s$)

• A. $1.5$
• B. $4$
• C. $1$
• D. $2$

Answer 1

The correct option is C $1$

Acoording to given graph,

Initial possition $r_1=0$

Final position $r_2=20m$

Net displacement $d=r_2-r_1=20-0=20m$

time taken $t=20s$

Thus average velocity $V_{avg}=\frac{Netdisplacement}{timetaken}=\frac{20}{20}=1m/s$

Option C
