CONCLUSION
The velocity and acceleration of the ball were much greater with a larger running start.  This makes the force, momentum, and work of the ball much greater with a running start as compared to a lesser distance of a running start.  This makes the ball go farther in a less amount of time.  Therefore, next time you're playin some soccer, get a bigger running start to kick the ball farther (if you want it to go farther).
