David Beckham Soccer Golf
Why shoot a free kick David Beckham's accuracy can reach 90%? Here it is the formula:
If Beckham's free kick is taken within 25 m from the goal, and the ball was kicked with a speed of 25 m / s, in this case led to spin the ball at a frequency of 10 rev / s. Assuming the air density 1.2 kg/m3 and diameter of the ball under the terms of FIFA 0.22 m, assuming the lift coefficient of 1.23 for the lift (elevator) or the magnus force can be calculated as follows.
FL = CLrD3fv
= 1,23 x 1,2 x 0,223 x 10 x 25
= 3,93 N
Acceleration of the ball can be calculated from the formula F = m.a
Mass of the ball by FIFA standards between 0.410 kg - 0.450 kg or 0.430 kg averaged.
F = m.a a = F/m = 3,93 / 0,430 = 9,14 m/s2
and its calculation is
