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: B = ‹ 3.18,
2.88, 0 › kg·m/s C = ‹ 2.7, 1.02, 0 › kg·m/s D = ‹ 2.39, ?0.52, 0 ›
kg·m/s E = ‹ 2.12, ?1.88, 0 › kg·m/s (a) Which of the diagrams
below correctly shows the graphical relationship between B , C ,
and ?...
