The position-time graph for a body moving along a straight line between $O$ and $A$ is shown in figure. During its motion between $O$ and $A$, how many times body comes to rest?

 The figure shows a velocity-time graph of a particle moving along a straight line. The particle comes to rest at $t=$ ……. $\sec$

A woman starts from her home at $9.00\; \mathrm{am}$, walks with a speed of $5\; \mathrm{km} h^{-1}$ on a straight road up to her office $2.5\; \mathrm{km}$ away, stays at the office up to $5.00 \;\mathrm{pm}$, and returns home by an auto with a speed of $25\; \mathrm{km} h^{-1}$. Choose suitable scales and plot the $x -t$ graph of her motion

The $v -t$ graph of a rectilinear motion is shown in adjoining figure. The distance from  starting point after $8$ seconds is ……….$metre$
