kicked directly toward a fence from a point
20 m away, as shown below.
The velocity of the ball as it leaves the
kickerâ ™s foot is 18 m/s at angle of 62 â—¦ above
the horizontal. The top of the fence is 9 m
high. The kickerâ ™s foot is in contact with the
ball for 0.06 s. The ball hits nothing while in
flight and air resistance is negligible.
The acceleration due to gravity is 9.8 m/s2.
Determine the magnitude of the average
net force exerted on the ball during the kick. Answer in units of N.
Also please determine the time of flight and how far above the fence will the ball fly (diameter of ball is negligible)
I'm completely lost, we haven't covered this stuff in class.
