$A$ racing car has a uniform acceleration of $4 \,m s^{-2}$. What distance (in $m$) will it cover in $10 \,s$ after start?

When will you say a body is in $(i)$ uniform acceleration? $(ii)$ nonuniform acceleration?

$A$ 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?

Joseph jogs from one end $A$ to the other end $B$ of a straight $300 \, m$ road in $2 \, min$ $30 \, sec$ and then turns around and jogs $100 \, m$ back to point $C$ in another $1 \, min$. What are Joseph's average speeds and velocities in jogging from $A$ to $B$?

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 $C$?

Under what condition$(s)$ is the magnitude of average velocity of an object equal to its average speed?
