Plot a velocity-time graph showing uniform retardation.

Which of the following graph is possible?

Interpret the regions $\mathrm{a}$, $\mathrm{b}$ and $\mathrm{c}$ in the following graph.

The time of arrival and departure of a train at three stations $\mathrm{A}$, $\mathrm{B}$ and $\mathrm{C}$ and the distance of stations $\mathrm{B}$ and $\mathrm{C}$ from $\mathrm{A}$ are given in the table.

Plot and interpret the distance-time graph for the train assuming that its motion between any two stations is uniform.

Study the velocity-time graph and calculate:

(a) The acceleration from $\mathrm{A}$ to $\mathrm{B}$

(b) The acceleration from $\mathrm{B}$ to $\mathrm{C}$

(c) The distance covered in region $\mathrm{ABE}$

(d) The average velocity from $\mathrm{C}$ to $\mathrm{D}$

(e) The distance covered in region $\mathrm{BCFE}$.

What do you mean by $5 \mathrm{m} {\mathrm{s}}^{-2}$?

A body starts from rest. What can be interpreted by this statement?
