Q$1(10$ pts$)$: A bird of mass $\backslash ($ m $\backslash )$ is flying in a straight line at height $\backslash ($ h $\backslash )$ with speed $\backslash ($ v $\backslash ).$ For specificity, set the origin to be on the ground $($so $\backslash ($ h$=0\backslash )$ would mean the bird is standing on the floor$).$ True or false $($circle one$)?$ The bird has angular momentum of zero. If true, explain why. If false, calculate the angular momentum of the bird.

True
