The sport of football is a fast passed, rough, and tumble sport. To play this game you must be fast, agile, strong, big, and intimidating. These things help but you must have an understanding of physic and its laws. Physics has an important part in every aspect of football, from running the football, all the way to kicking off and punting football. Even tackling and taking a hit has to do with physics. Football is physics in a form that everyone can understand. It is a living and breathing example of everyday physics.
When punting and kicking off the ball physics is need to get desired results. When punting the football the kicker starts with the ball in his hand. It is necessary to kick the ball far and have enough hang time for your defensive lineman to get down the field to prevent the run. This is important because if the ball isn't kicked with enough with enough hang time, the offense will return the punt for a long gain. Then you will have less field to stop their drive. When kicking off the objectives are the same but not quite that same. When kicking off you want to kick the ball longer then having a lot of hang time. The ball starts from a stationary position on the ground. Then the kicker kicks it down field to the opposing team. He must get the ball to go far and in a have the right amount of hang time to prevent a good run.
The weight of the football, the angle at which it is kicked, and the speed are all important parts of kicking. This is what we know.
The weight is = 5.7kg.
The I velocity=27m/s.
The f velocity=0m/s.
The acceleration=9.81m/s2 .
Time=?.
Range is unknown.
We must use the formulas.
1.Vf=vi+at.
2.VF2=VI2+2ad.
3.Range=vx (total time).
4.Vx=VcosA Vy=VsinA.
First I had to use the speed to find out the velocity for the x and y-axis. Once that was done I used formula number 1 to find the total time. Then I used formula number 2 to find the height of the football. I multiplied the Vx and the total time to get the range/ how far the ball traveled (all working showed on board).
