Draw a displacement-time graph for a girl going to market with a uniform velocity.

State how the velocity-time graph can be used to find the displacement of the body in a given time interval.

State how the velocity-time graph can be used to find the acceleration of the body.

Two athletes are moving along a straight track. A figure shown below represents a displacement-time graph to display the movement of these two athletes. Find out who is moving faster. Give reason.

A particle moves $12 \mathrm{m}$ to east and then through $5 \mathrm{m}$ to north. Now, the net displacement is $K \mathrm{m}$. Find the value of $K$.

A body starts from rest and acquires a velocity $10 \mathrm{m} {\mathrm{s}}^{-1}$ in $2 \mathrm{s}$. Find acceleration of the body in $\mathrm{m} {\mathrm{s}}^{-2}$
