Question

A circular disc of radius 4m making 600 evolution per minute. Calcuate angular velocity of disc.

Answer 1

The angular velocity and the linear velocity of the disc is 62.83 rad/s and 251.32 m/s respectively.

Explanation:

Given that,

Radius of the circular disc, r = 4 m

Angular velocity of the disc is 600 revolution per minute. We can convert it into radian per second as :

$\omega=62.83\ rad/s$

We can find the linear velocity of the disc using the below relation as :

$v=r\omega$

$v=4\ m\times 62.83\ rad/s$

v = 251.32 m/s

So, the angular velocity and the linear velocity of the disc is 62.83 rad/s and 251.32 m/s respectively.
