Answer:

Possible Answers:

5 m/s

4 Hz

100 Hz

14 Hz

Step-by-step explanation:

Step-by-step explanation:

Using the equation,

ω=vr where

ω=angular velocity, v=linear velocity, and r=radius of the circle.

In this case the radius is 5 (half of the diameter) and linear velocity is 20 m/s.

ω=205=4.
