SUMMARY
The fireman must aim the hose at an angle of approximately 53.1 degrees relative to the horizontal to ensure the water reaches the burning wall at the same height of 20 meters. Given a horizontal velocity of 12 m/s, the required angle can be calculated using projectile motion equations. The discussion emphasizes the importance of understanding trajectory calculations in physics, particularly in real-world applications like firefighting.
