Final answer:
To find the angular velocity from linear velocity and radius, you can use the equation w = v / r.
Step-by-step explanation:
To find the angular velocity (w) from linear velocity (v) and radius (r), you can use the equation v = rw. Rearranging the equation, we have w = v / r. For example, if the linear velocity is 15.0 m/s and the radius is 0.300 m, the angular velocity is calculated as 15.0 m/s / 0.300 m = 50.0 rad/s.
