The velocity-time graph of a body moving in a straight line is shown in the figure. The displacement and distance travelled by the body in $6 \, s$ are respectively:

Which of the following position-time $(s-t)$ graphs represents uniform acceleration?

$A$ train starting from rest travels the first part of its journey with constant acceleration $a$,the second part with constant velocity $v$,and the third part with constant retardation $a$,finally being brought to rest. The average speed for the whole journey is $\frac{7v}{8}$. The train travels with constant velocity for what fraction of the total time?

Between two stations,a train accelerates uniformly at first,then moves with constant velocity,and finally retards uniformly. If the ratio of the time taken is $1 : 8 : 1$ and the maximum speed attained is $60\,km/h,$ what is the average speed over the whole journey in $km/h$?

The velocity $(v)$ - distance $(x)$ graph is shown in the figure. Which graph represents the acceleration $(a)$ versus distance $(x)$ variation of this system?

What is the acceleration of the particle on $OA$,$AB$,and $BC$ respectively?
