Swinging road - harmonical movement

[Kosta1234]

Homework Statement

please check if my answer is ok.
There is a rod, with length L and maximum angle α swinging from the ceiling and making harmonical movement.
What is the angular velocity of the movement?

Homework Equations

ω = sqrt (g/l)

The Attempt at a Solution

that is the answer?
it's weird because we learn now angular momentum, torque and rigid body, and my answer has nothing to do with that.thank you.

You have a physical pendulum. See

On edit: You are looking for the angular frequency of oscillations, not the angular velocity of the movement. The two are quite different concepts.
