In the following velocity-time graph,the distance travelled by the body in metres is ............. $m$.

$A$ bird flies with a velocity $(t-2) \text{ m/s}$ along a straight line, where $t$ is the time in seconds. The distance covered by it in a time of $4 \text{ s}$ is: (in $\text{ m}$)

$A$ small electric car has a maximum constant acceleration of $1\,m/s^2$,a maximum constant deceleration of $2\,m/s^2$,and a maximum speed of $20\,m/s$. The amount of time it would take to drive this car $1\,km$ starting from rest and finishing at rest is $.........\,s$.

The velocity-time and acceleration-time graphs of a particle are given. Its position-time graph may be given as:

Draw the $v-t$ graph for constant velocity and explain it.

An object at rest at the origin begins to move in the $+x$-direction with a uniform acceleration of $1 \, m/s^2$ for $4 \, s$ and then it continues moving with a uniform velocity of $4 \, m/s$ in the same direction. The $x-t$ graph for the object's motion will be:
