21. We use coordinates with +xhorizontally toward the pitcher and +yupward. Angles are measured counterclockwise from the +xaxis. Mass, velocity and momentum units are SI. Thus, the initial momentum can be written Gp04 5215=∠°.bgin magnitude-angle notation.(a) In magnitude-angle notation, the momentum change is (6.0∠– 90°) – (4.5
