Question

A particle moves in a circle of radius 20 cm with linear speed of 10 m per second .find the angular velocity

Answer 1

Given data,

Radius of circular path ,

r = 20cm = 0.2m

linear speed of particle moves in circular path ,

v = 10m/s

we know, formula

$w = \frac{v}{r}$

where w is angular velocity, v is linear velocity of particle and r is the radius of circularpath,

$w = \frac{v}{r}$

= 10/0.2 = 50 rad/s

hence, angular velocity of particle is 50 rad/s

Hope this will help u..
