Question

The object starts from $O$ having a straight line motion along the path $OPQRS$ is represented by the distance-time graph shown in figure. Match the given statements to the different parts of the graph correctly.
(i) Object is moving with maximum speed.
(ii) Object starts moving in reversed direction.
(iii) Object is at rest.
(iv) Average velocity of object is zero.

• A. $\left(i\right)-OS,\left(ii\right)-OP,\left(iii\right)-RS,\left(iv\right)-PQ$
• B. $\left(i\right)-OP,\left(ii\right)-RS,\left(iii\right)-QR,\left(iv\right)-OS$
• C. $\left(i\right)-PQ,\left(ii\right)-RS,\left(iii\right)-OP,\left(iv\right)-QR$
• D. $\left(i\right)-QR,\left(ii\right)-PQ,\left(iii\right)-OS,\left(iv\right)-OP$

Answer 1

The correct option is B $\left(i\right)-OP,\left(ii\right)-RS,\left(iii\right)-QR,\left(iv\right)-OS$

During $OP$, distance travelled is maximum for small time interval. During, $RS$, distance travelled is in reverse direction. During $QR$, object is at rest as time passes, distance is fixed. During $OS$, displacement is zero, hence velocity will be zero.
