What can you say about the motion of an object whose distance-time graph is a straight line parallel to the time axis?

$A$ bus starting from rest moves with a uniform acceleration of $0.1\, m s^{-2}$ for $2\, min$. Find $(a)$ the speed acquired,$(b)$ the distance travelled.

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

$A$ driver of a car travelling at $52\, km\, h^{-1}$ applies the brakes and accelerates uniformly in the opposite direction. The car stops in $5\, s$. Another driver going at $3\, km\, h^{-1}$ in another car applies his brakes slowly and stops in $10\, s$. On the same graph paper,plot the speed versus time graphs for the two cars. Which of the two cars travelled farther after the brakes were applied?

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

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 $C$?
