A small 0.300kg bird is flying horizontally at 3.50m/stoward a 0.750kg thin bar hanging vertically from a hook at its upper end.
When the bird is far from the bar, what are the magnitude and direction (clockwise or counterclockwise) of its angular momentum about a horizontal axis perpendicular to the plane of the figure and passing through point C?

Let counterclockwise angular momentum be positive, clockwise angular momentum be negative.
