9 m/s 35° The last segment of the triple jump track-and-field event is the jump, in which the athlete makes a final leap, landing in a sandfilled pit. Assuming that the velocity of a 80-kg athlete just before landing is 9 m/s at an angle of 35° with the horizontal and that the athlete comes to a complete stop in 0.22 s after landing, determine the horizontal component of the average impulsive force exerted on his feet during landing.

**Understanding the Physics of the Triple Jump Landing**

The final phase of the triple jump in track and field is the landing, where the athlete completes a final leap into a sand-filled pit. To analyze the physics involved, let's consider a scenario:

Imagine an athlete weighing 80 kg with a velocity of 9 m/s, making an angle of 35° with the horizontal, just before landing. After landing, the athlete stops completely within 0.22 seconds. Our goal is to determine the horizontal component of the average impulsive force exerted on the athlete's feet during this landing.

**Illustration Description:**

The diagram shows an athlete in mid-air, about to land in a sand pit:

- The athlete is depicted at an angle of 35° to the horizontal, with a velocity vector labeled 9 m/s.
- Upon landing, the athlete's trajectory and posture are visualized.
- The landing pit is highlighted, indicating the point of contact with the sand.

This scenario provides an excellent opportunity to apply principles of physics such as impulse and momentum to calculate the forces involved in athletic events.
