$A$ train starting from a railway station and moving with uniform acceleration attains a speed $40 \, km \, h^{-1}$ in $10$ minutes. Find its acceleration (in $m / s^{2}$).

The figure shows the distance-time graph of three objects $A$,$B$,and $C$. Study the graph and answer the following questions:
$(a)$ Which of the three is travelling the fastest?
$(b)$ Are all three ever at the same point on the road?
$(c)$ How far has $C$ travelled when $B$ passes $A$?
$(d)$ How far has $B$ travelled by the time it passes $C$?

What is the quantity which is measured by the area occupied below the velocity-time graph?

Distinguish between speed and velocity.

$A$ stone is thrown in a vertically upward direction with a velocity of $5 \, m s^{-1}$. If the acceleration of the stone during its motion is $10 \, m s^{-2}$ in the downward direction,what will be the height attained by the stone and how much time will it take to reach there?

What does the path of an object look like when it is in uniform motion?
