1
FOOTBALL AND FUNCTIONAL DEPENDENCE

2
TASK: A Football player passes the ball to his teammate. Determine on what depends the length of the flight of the ball.

3
40 L h 30 45 60

4
Yox=Vo cos V OY =V O sin y VoVo V oy x V ox

5
SOLUTION: At max h => V y = 0 V y =V 0 sin - gt = 0 => t raising = V 0 sin _______________ g t flight =2 t raising L= x = (V 0 cos ) t flight 2 L= V 0 cos 2 V 0 sin = V 0 2 sin cos _______________________ _____________________________________________ g g 2 L= V 0 sin 2 _________________________ g

6
The length of the flight 2 depends on the targeted initial speed V 0 and on the value of angle Lmax => sin2=1 => 2 =90 => =45 At V 0 =20 m/s L max =40m Comment: (the air resistance is neglected)
