Final answer:
The angular velocity of the cyclist is
radians per second.
Explanation:
The angular velocity is a measure of how quickly an object rotates or moves in a circular path. In this scenario, the cyclist completes q lap around the track in 20 seconds. Angular velocity is defined as the angle covered in a given time.
For one complete lap, the angle covered is
radians (a full circle), and as the cyclist completes q laps in 20 seconds, the angular velocity is calculated as

, which simplifies to
radians per second. This denotes the rate of change of angle per unit of time.
The angular velocity of the cyclist is
radians per second.
