How long will it take to complete a circle? How many radians in a full circle?

What is your understanding of the definition of a radian? If you have an arc of a circle of length s, and the radius of the circle is r, what is the angle in radians that is subtended by the arc?

I don't understand you're question, Shania, m/s is a unit for velocity, but radians is a unit for angle measurement.
What is you're interpretation of angular velocity?
