Welcome to the PF. We don't do your homework for you, but we can offer some tutorial hints. What is the definition of the impulse? What is the equation that describes the impulse? What is different in (a) that would affect the impulse? How about (b) and (c)?

Impulses are a fundamental concept in physics that describe the change in momentum of an object over time. In terms of sports, impulses can be thought of as the force applied to an object, such as a golf club or a fist, to cause it to accelerate and move.

In a golfer's long drive, a large impulse is applied to the golf club during the swing. This impulse causes the club to accelerate and generate a high velocity, resulting in a long and powerful shot. On the other hand, in a short chip shot, a smaller impulse is applied to the club, resulting in a lower velocity and a shorter shot. The difference in the length of the shot is due to the difference in the magnitude of the impulse applied.

Similarly, in boxing, a boxer's jab is a quick, short punch that applies a small impulse to the opponent's face. This may not result in a significant change in momentum, but it can be used to set up a more powerful knock-out punch. A knock-out punch, on the other hand, is a strong and forceful punch that applies a larger impulse to the opponent, resulting in a greater change in momentum and potentially knocking them out. The difference in the strength of the punch is due to the difference in the magnitude of the impulse applied.

In baseball, a bunting action involves lightly tapping the ball with the bat, applying a small impulse to the ball to redirect it and advance a runner. This is in contrast to a homerun swing, where a large impulse is applied to the ball, resulting in a high velocity and a long-distance hit. The difference in the outcome is again due to the difference in the magnitude of the impulse applied.

In conclusion, impulses play a crucial role in differentiating between the length, strength, and outcome of various actions in sports. Understanding the concept of impulses can help athletes improve their performance by adjusting the magnitude of their impulses to achieve their desired results.
