For a body moving along a straight line, the following $v-t$ graph is obtained.

According to the graph, the displacement during

A particle starts from rest. Its acceleration $a$ versus time $t$ is shown in the figure. The maximum speed of the particle will be:

The given graph shows the variation of velocity $\left(v\right)$ with position $\left(x\right)$ for a particle moving along a straight line

Which of the following graph shows the variation of acceleration $\left(a\right)$ with position $\left(x\right)?$
