1. What is the magnitude of the average angular velocity of the eye?

!
Required information
The ability of the human eye to rapidly rotate was studied using contact lenses fitted with accelerometers. While a
subject, whose eyeball has radius 1.25 cm, watches a moving object her eyeball rotates through 20.0° in a time
interval of 57.5 ms.

Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.
