Question
Two runners are racing around a cicular track. The first runner is in the inside lane. The second runner is in the outside lane. If the first runner wants to stay side-by-side with the second runner, what does her angular velocity need to be?
Question 4 options:
Her angular velocity must be less than the second runner's.
Her angular velocity must be the same as the second runner's.
Her angular velocity must be greater than the second runner's.
We can't say without knowing the radius of the track.

Explanation / Answer
The angular velocity needs to exactly the same as they would then cover equal angular distance for a period of time. An equal angular distance means that would always be side to side.
