SUMMARY
The discussion focuses on calculating the maximum height of a projectile launched at a 30-degree angle with an initial speed of 0.714 m/s. The participant utilized the kinematic equation V² = V₀² + 2ad to derive a height of 19.49 meters, which was deemed impractical. The error was identified in the application of the equation, specifically in the calculation of the vertical component of the initial velocity and the interpretation of the results. Correctly, the maximum height should be calculated using d = V₀² / (2g), leading to a more realistic value.
