Problem 2PE

Microwave ovens rotate at a rate of about 6 rev/min. What is this in revolutions per second? What is the angular velocity in radians per second?

Solution 2PE

We are required to calculate the rotation of a microwave oven in revolutions per second. We also have to calculate the angular velocity in radians per second.

Step 1 of 2</p>

The rate of rotation of the ovens is 6 rev/min

1 min 1 min s/min

1 min 60 s

Therefore, the rotation of the ovens rev/60 s

rev/s

The microwave ovens have a rotation of 0.1 revolutions per second.
