Distance$-$time graph below represents the motion of two buses $A$ and $B$

$(i)$ What is the distance by which bus $B$ was ahead of bus $A$ initially ?

$(ii)$ Do they ever meet each other ? If so, when ?

$(iii)$ What is the distance travelled by bus $A$ when it overtakes bus $B$ ?

$(iv)$ Find out the distance by which bus $A$ was ahead of bus $B$ at $y=12 h$

$(v)$ Which one of them is moving faster ? Give reason.

An object is moving along a straight line with uniform acceleration. The following table gives the velocity of the object at various instants of time

Plot the graph.

From the graph.

$(i)$ Find the velocity of the object at the end of $2.5 sec$

$(ii)$ Calculate the acceleration.

$(iii)$ Calculate' the distance covered in the last $4$ sec.

A body can have zero average velocity but not zero average speed. Justify giving an example.

Under what condition will the magnitude of the displacement be equal to the distance travelled by an object ?

The direction of acceleration of an object moving in a circular path is
