Learning Goal:
To practice Problem-Solving Strategy 9.1 A strategy for conservation of momentum problems.
An 80-kg quarterback jumps straight up in the air right before throwing a 0.43-kg football horizontally at 15 m/s . How fast will he be moving backward just after releasing the ball?
Part F
Suppose that the quarterback takes 0.30 s to return to the ground after throwing the ball. How far d will he move horizontally, assuming his speed is constant? Answer in meters.
