Question

A body moves along the curved path of a quarter circle.calculate the ratio of distance and displacement

Answer 1

Distance =
$\pi {r}^{2}$
Displacement =
$r \sqrt{2}$
Distance /Displacement =
$\pi \: r \div 2r \sqrt{2} = (\pi \sqrt{2}) \div 4$
Ratio of distance and displacement is pi :2 root 2
