SUMMARY
The discussion centers on calculating the height of a 12 kg meteor experiencing an acceleration of 7.2 m/s² as it falls towards Earth. Using the gravitational formula \( g = \frac{G \cdot M_{Earth}}{r^2} \), the user correctly derives the distance from the center of the Earth to the meteor as approximately 7.4 x 10⁶ m. Subtracting Earth's radius of 6.36 x 10⁶ m results in a height of 1.06 x 10⁶ m, or 1060 km, above the Earth's surface. A key insight is that the mass of the meteor is irrelevant for this calculation.
