Answer: The magnitude of the force exerted by the ball on the kicker's foot is of 769.99 Newtons.
Explanation:
Mass of the football = 0.49 kg
Initial velocity of the ball ,u= 0 m/s
Final velocity of the ball ,v= 44 m/s
time of contact ,t = 0.028 seconds
First law of motion:
v=u+at
[tex]44 m/s=0+a\times 0.028 sec[/tex]
[tex]a=1,571.42 m/s^2[/tex]
[tex]force=mass\times acceleration=0.49 kg\times 1,571.42 m/s^2=769.99N[/tex]
The magnitude of the force exerted by the ball on the kicker's foot is of 769.99 Newtons.
