Question

A car moves round a circular track of radius 0.3m of two revolution per/sec find its angular velocity.

​

Answer 1

the angular velocity of the car is 12.568 rad/s.

Step-by-step explanation:

Given;

radius of the circular track, r = 0.3 m

number of revolutions per second made by the car, ω = 2 rev/s

The angular velocity of the car in radian per second is calculated as;

From the given data, we convert the angular velocity in revolution per second to radian per second.

`\omega = 2 \ (rev)/(s) * (2\pi \ rad)/(1 \ rev) = 4\pi \ rad/s = 12.568 \ rad/s`

Therefore, the angular velocity of the car is 12.568 rad/s.
