From the given $v-t$ graph (Fig.),it can be inferred that the object is

$A$ car starts from rest and moves along the $x-$ axis with constant acceleration $5\, ms^{-2}$ for $8\, s$. If it then continues with constant velocity,what distance will the car cover in $12\, s$ since it started from the rest (in $m$)?

Explain the following types of motion with one example for each:
$(i)$ Acceleration is positive
$(ii)$ Acceleration is negative
$(iii)$ Acceleration is zero.

What conclusion can you draw from the displacement$-$time graph of a body as shown below?

Can the distance travelled by a particle be zero when displacement is not zero?

Starting from rest,a scooter acquires a velocity of $36 \, km/h$ in $10 \, s$ and then brakes are applied,taking $20 \, s$ to stop. Calculate the acceleration and the total distance travelled.
