Question

The big tires on a farmer's tractor have a radius of 1.2 meters. If the farmer drives his tractor at 4.2 m/s to the left, what is the angular velocity of the tires?

Answer 1

Angular velocity = 3.5 rad/secs

Step-by-step explanation:

Given the following data;

Radius, r = 1.2 meters

Linear velocity = 4.2 m/s

To find the angular velocity;

Mathematically, angular velocity of an object is given by the formula;

`Angular \; velocity = \frac {linear \; velocity}{radius}`

Substituting into the formula, we have;

`Angular \; velocity = \frac {4.2}{1.2}`

Angular velocity = 3.5 rad/secs
