The figure above shows a portion of the trajectory of a ball traveling through the air. Arrows indicate its momentum at several locations. At these locations, the ball's momentum is: p^vector_B = < 3.13, 2.88, 0 > kg middot m/s p^vector_C = < 2.65 1.02, 0 > kg middot m/s p^vector_D = < 2.34 -0.52, 0 > kg middot m/s p^vector_E = < 2.07, -1.88, 0 > kg middot m/s (a) which of the diagrams below correctly shows the graphical...
