To find angular velocity experimentally using a boomerang, recording the flight with a video camera can be helpful, although the rapid movement may complicate this method. Multiple cameras could provide a better view of the rotation throughout the flight path. However, practical limitations in a classroom setting may restrict the feasibility of recording. An alternative approach could involve using a simpler setup or tools that allow for easier measurement of angular velocity. Ultimately, the experiment needs to be manageable for the entire class within the available time.
