The area under an acceleration-time graph gives:

The figure shows a velocity-time graph of a particle moving along a straight line. The total distance travelled by the particle is ........ $m$.

For the following velocity-time graph, the average speed for the motion during first $80 \, s$ is

The position-time $(x-t)$ graphs for two children $A$ and $B$ returning from their school $O$ to their homes $P$ and $Q$ respectively are shown in the figure. Choose the correct entries in the brackets below:
$(a)$ $(A/B)$ lives closer to the school than $(B/A)$
$(b)$ $(A/B)$ starts from the school earlier than $(B/A)$
$(c)$ $(A/B)$ walks faster than $(B/A)$
$(d)$ $A$ and $B$ reach home at the (same/different) time
$(e)$ $(A/B)$ overtakes $(B/A)$ on the road (once/twice)

The distance covered by the particle in the last $2\,s$ is what fraction of the total distance covered by it in $7\,s$?

The graph shows the variation of velocity of a rocket with time. The maximum height attained by the rocket is ........... $km$ :-
