Question

An athlete performing the long jump tries to achieve the maximum distance from the point of takeoff to the first point of touching the ground. After the jump, rather than land upright, she extends her legs forward as in (Figure 1). How does this affect the time in the air? How does this give the jumper a longer range?

Explanation / Answer

Solution:

By extending their legs forward, the runners increase their time in the air. The “center of mass” of a projectile follows a parabolic path.

By raising their feet so that their feet are closer to their center of mass, the runners increase the time it takes for their feet to hit the ground. By increasing their time of flight, they increase their range. Also, having their feet ahead of them means that their feet will land ahead of where they would have landed otherwise.

By simply moving their feet,runners can change their time of flight and change the spot where their feet land.
