Derive an equation that can be integrated to find the angular velocity of the bar as it passes through the vertical position. The image is of a bar that is released from horizontal rest, spins clockwise. It is asking for when the bar is at a vertical position. At the top is point A, then L/4 down is point C (which is the location of the pin which the bar rotates about) and then 3L/4 down is the bottom of the bar, point B. The bar is uniform and has length L and mass m. All variables, no numbers.
