Final answer:
The question about turbojet minimum dispatch landing distance is not directly related to the physics problems described in the scenarios provided, which involve tire rotation speeds, position vectors, and land coverage for wind turbines.
Step-by-step explanation:
The question relates to the disciplines of engineering and physics, specifically encompassing areas such as aircraft operation and aerodynamics commonly studied in high school physics or aviation-related courses. The minimum dispatch landing distance required at the aerodrome for a turbojet, which is depicted amongst the options 40%, 50%, 60%, and 70%, is not directly answered within the standard high school physics curriculum, and thus cannot be determined from the information provided in all three question scenarios. These scenarios instead describe different physics problems: (1) calculating tire rotation speed at a given velocity, (2) determining position vectors and distance between two airplanes, and (3) calculating land coverage fraction for wind turbines based on their separation.
