Final answer:
The question asks for calculating position vectors and the distance between two aircraft from a control tower's perspective, requiring knowledge of college-level physics.
Step-by-step explanation:
The question involves calculating the position vectors of two airplanes relative to a control tower and determining the distance between them, which requires an understanding of trigonometry and vector mathematics typically covered under college-level physics. The question asks for calculating position vectors and the distance between two aircraft from a control tower's perspective, requiring knowledge of college-level physics.
To calculate the position vectors for the Boeing 747 and the DC-3, we must use trigonometric functions to resolve the given information into horizontal and vertical components. Finding the distance between the planes would involve vector subtraction and the use of the Pythagorean theorem or vector norms.
