Final answer:
The original question pertains to sports rules that are not provided, but physics principles can explain a scenario where a goalkeeper kicks a ball towards the opponent's goal, covering a distance influenced by the initial speed and the kick angle.
Step-by-step explanation:
The question asks to analyze several scenarios involving a ball hitting the net above the boards or turf in different positions on the field. This requires an understanding of the rules of the game, which could be soccer or a similar sport, rather than a physics-based analysis. Without information on specific sports rules, we can't provide a factual answer. However, we can discuss the physics of projectile motion through an example of a soccer ball being kicked.
For instance, when a goalkeeper kicks a soccer ball towards the opponent's goal without the ball touching the ground, the distance covered depends on various factors, including the initial speed of the ball, the angle of the kick, and resisting forces like air friction. Assuming no air resistance and optimum conditions, a goalkeeper kicking a ball at a 30 m/s speed may cover a distance of approximately 95 m, but only if the kick angle and conditions are just right.
However, in a normal game situation, many variables would affect the ball's flight, and it is unlikely (though not impossible) for a goalkeeper to score from their own goal without any bounces.
