How do you find angular velocity experimentally?

[jjellybean320]

if I were to throw a boomerang in an experiment, how would i find the angular velocity? How would i be able to check that my angular velocity is correct?

Get a video camera and record it to see how fast it rotates? It might be hard because the boomerang moves away from you very quickly, so perhaps have multiple cameras recording along the entire flight path.

i don't think that would work because i have to devise a boomerang experiment to be done by the rest of the class. so I wouldn't have the time in class to have everyone record the boomerang flight.
