Question

A particle goes from A to B moving in a semicircle path of radius 1m.Find average velocity.

Answer 1

Given : $r=1m$

Velocity $=\frac{displacement}{time}$

Displacement $=\frac{2\pi r}{2}$

$=\pi r$

$=3.14\times 1$

$=3.14m$

Let us assume,

$t=1sec$

$\therefore$ velocity $=\frac{3.14}{1}$

$=3.14m/s$

$V=3.14m/s$
