V K Sally and R Goel Solutions for Chapter: Motion, Exercise 3: EXERCISE

A boy running around a circular track of radius $7 \mathrm{m}$ returns back to the starting point after completing two rounds. The distance covered by the boy and the displacement is : (Take the value of $\mathrm{\pi }$ as $\frac{22}{7}$)

If a person could fly non-stop around the equator of earth and reaches back at initial point, the displacement is:

A boy walks around a circular track of radius $14 \mathrm{m}$, such that after $2$ minutes he is diametrically opposite to the starting point.
