As you stand on the sidewalk outside an apartment building, a 2.0-kg bird flies toward you at 2.5 m/s along a straight line that passes 3.0 m above your head and runs parallel to the street. A friend is reclining with his head 4.0 m directly above your head, watching from a balcony. What angular momentum do you observe the bird to have, using your head as a reference point Express and what angular momentum does your friend observe the bird to have, using his own head as a reference point
