Question

Самолет стартовал с Северного полюса, пролетел вдоль меридиана до экватора, а затем пролетел еще 3000 км вдоль экватора на запад. Найдите модуль перемещения самолета в системе отсчета, связанной с Землей. Есть ли в условии лишние данные?

Answer 1

Перемещение самолёта в данном случае - это расстояние от Северного полюса до конечной точки на экваторе. Это расстояние равно приблизительно 10000 км.

Лишние данные есть - неважно, сколько самолёт пролетел вдоль экватора, модуль перемещения не изменится.

Answer 2

Calculating the Displacement of the Aircraft

To calculate the displacement of the aircraft in the Earth-centered reference frame, we can break down the given scenario into its components and calculate the total displacement.

1. From the North Pole to the Equator: - The distance from the North Pole to the Equator is the radius of the Earth, which is approximately 6,371 kilometers.

2. Along the Equator: - The aircraft flew an additional 3,000 kilometers along the Equator to the west.

3. Total Displacement: - The total displacement of the aircraft in the Earth-centered reference frame can be calculated by adding the displacement from the North Pole to the Equator to the displacement along the Equator.

Calculating the Total Displacement

The total displacement of the aircraft in the Earth-centered reference frame can be calculated as follows:

Total Displacement = Displacement from North Pole to Equator + Displacement along Equator

Displacement from North Pole to Equator = 6,371 kilometers

Displacement along Equator = 3,000 kilometers

Total Displacement = 6,371 kilometers + 3,000 kilometers

Total Displacement = 9,371 kilometers

Conclusion

The total displacement of the aircraft in the Earth-centered reference frame, considering the given scenario, is 9,371 kilometers.

Extra Data in the Given Scenario

The given scenario does not contain any extra data. All the provided information is relevant to calculating the displacement of the aircraft in the Earth-centered reference frame.
