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

The position of a particle moving along the $y-$ axis is given as $y = 3t^2 - t^3$,where $y$ is in $m$ and $t$ is in $s$. The time when the particle attains the maximum positive position will be ........ $s$.

From the $v-t$ graph,the

The position-time $(x-t)$ graph for positive acceleration is

The $x-t$ equation is given as $x = 2t + 1$. The corresponding $v-t$ graph is:

$A$ train starting from rest accelerates uniformly for $100\,s,$ then comes to a stop with a uniform retardation in the next $200\,s.$ During the motion,it covers a distance of $3\,km.$ Choose the wrong option.
