The $v-t$ graph of a rectilinear motion is shown in the adjoining figure. The distance from the starting point after $8 \text{ s}$ is .......... $\text{m}$.

$Assertion$ : Velocity-time graph for an object in uniform motion along a straight path is a straight line parallel to the time axis.
$Reason$ : In uniform motion of an object velocity increases as the square of time elapsed.

The figure shows $(v_x, t)$ and $(v_y, t)$ diagrams for a body of unit mass $(m = 1 \text{ kg})$. Find the force as a function of time.

If a steel ball is dropped from a height onto a marble floor,what will the velocity-time graph look like?

Which of the following position-time $(s-t)$ graphs represents uniform acceleration?

The velocity-time $(v-t)$ graph for a moving object is shown in the figure. The total displacement of the object during the time interval when there is non-zero acceleration and retardation is ........ $m$.
