A body moves in a circular path of radius 'r'. After completing one full rotation, its displacement is:

A person moves 30 m north and then 20 m towards east and finally $30\sqrt 2 \,\,m$ in south-west direction.

The displacement of the person from the origin will be

A particle's position vector is given by $\vec{r}(t) = (3t^2 - 2t)\hat{i} + (t^3 - 4)\hat{j}$. At what time $t$ is the particle's displacement from the origin equal to 5 units?

A cyclist moves in such a way that he track ${60^0}$ turn after 100 m. What is the displacement when to takes seventh turn?

A body is moving along the circumference of a circle of radius '$R$' and completes half of the revolution. Then the ratio of its displacement to distance is
