Describing Motion

Joseph jogs from one end A to the other end B of a straight $300 \mathrm{m}$ road in $2 \mathrm{m}\mathrm{i}\mathrm{n}$ $30 \mathrm{s}$ and then turns around and jogs $100 \mathrm{m}$ back to point C in another $1 \mathrm{m}\mathrm{i}\mathrm{n}$. What are Joseph’s average speeds and velocities in jogging from A to C?

Which of the following is true for displacement?
(a) It cannot be zero.
(b) Its magnitude is greater than the distance travelled by the object.

A farmer moves along the boundary of a square field of side $10 \mathrm{m}$ in $40 \mathrm{s}$. What will be the magnitude of displacement of the farmer at the end of $2 \mathrm{minutes} 20 \mathrm{seconds}$from his initial position?

An object has moved through a distance. Can it have zero displacement? If yes, support your answer with an example.

What does the odometer of an automobile measure?
