In their search for the missing rocket, Homer and Quentin use trajectory formulas for a free-falling projectile influenced only by gravity. That might have been appropriate for a cannonball. A rocket, providing its own thrust during flight, is not free-falling. Since the rockets were launched vertically (angle of elevation 90°), Homer's own misapplied range formula would have resulted in zero, exactly what one would expect for a projectile thrown directly upward.In his classroom explanation, Homer does correctly derive an approximation for the maximum height, based on the time it took to fall back down, but that does not address the question. His case actually turns on their recovery of the rocket and the range records for the other rockets.
