The velocity-time graph of a particle in one-dimensional motion is shown in the figure. Which of the following formulae is correct for describing the motion of the particle over the time interval `t_1` to `t_2`?

Explanation

From the graph we note that the slope that the slope is mot constant and is not uniform and is not uniform, hecne the relation (i), (ii) and (v) and are not correct, but the relations (iii), (iv) and (vi) are correct.
