The goal of this experiment is to calculate velocity and acceleration using human motion. The accuracy in measuring off 100 meters.
Runners get tired.

Person Method Measuring 100 meters with a meter stick and breaking the length into four equal parts using the chalk accomplished our objective. The points being at 25m, 50m, 75m, and 100m.
