The ladder of mass m and length L is released from rest at the angle θ0. Model the ladder as a uniform slender bar.

If the friction at O between the ladder and the ground is sufficient to prevent slipping, and the ladder is given a slight nudge from rest at θ = 90°, determine the angular speed of the ladder when it reaches θ = 0.
