To practice Problem-Solving Strategy 11.1 for conservation of momentum problems. An 80-kgkg quarterback jumps straight up in the air right before throwing a 0.43-kgkg football horizontally at 15 m/sm/s . How fast will he be moving backward just after releasing the ball?Which of the following best describes why you can analyze this event using conservation of momentum?
a. The throwing action is quick enough that external forces may be ignored.
b. External forces don't act on the system during the jump.
c. Conservation of momentum is always the best way to analyze motion.
