An object is moving with variable speed,then

The position-time graph for a body moving along a straight line between $O$ and $A$ is shown in the figure. During its motion between $O$ and $A$,how many times does the body come to rest?

The acceleration-time graph of a body is shown. The corresponding velocity-time graph of the same body is

From the $v-t$ graph,find the total distance covered by the car in time $t = t_1 + t_2$.

The velocity-time graph of a body moving in a straight line is shown in the figure. The ratio of displacement to distance travelled by the body in time $0$ to $10\,s$ is

The graph shows the variation with time $t$ of velocity $v$ of an object moving along a straight line. The $a-t$ graph will be:
