Linear velocity?

Question

The angular velocity of  wheel of a tractor is 18 rev/min. Find the linear velocity in meter/sec on the rim if the radius of the wheel is 100 meters.

 

Answer 1

The angular velocity .

To convert rpm (revolutions per minute) to radians per second, first note that there are radians per revolution.

The relation between is , where r is the radius of the wheel.

Here the angular velocity must use radians.

Linear velocity .
