Question

Самолет летит на север со скоростью 300 км.час относительно воздуха через воздушный поток, движется на запад со скоростью 50 км.час. Какой путь пролетит самолет за 2 часа ?

Answer 1

Модуль суммарного вектора скорости составит (300^2+50^2)^(1/2) = 50√37 км/ч
за два часа самолёт пролетит 100√37 км

Answer 2

300 - 50 = 250(км/ч) пролети за 1 час
250 * 2 = 500(км)
Ответ:500 км

Answer 3

Calculation of the Plane's Path

To calculate the path traveled by the plane, we need to consider its velocity relative to the air and its velocity in the westward direction.

Given: - Velocity of the plane relative to the air (northward): 300 km/h - Velocity of the plane in the westward direction: 50 km/h - Time: 2 hours

To find the total distance traveled by the plane, we can use the formula:

Distance = Velocity x Time

Let's calculate the distance traveled in each direction and then find the total distance.

1. Distance traveled northward: - Velocity relative to the air: 300 km/h - Time: 2 hours - Distance = 300 km/h x 2 hours = 600 km

2. Distance traveled westward: - Velocity in the westward direction: 50 km/h - Time: 2 hours - Distance = 50 km/h x 2 hours = 100 km

Now, let's find the total distance traveled by the plane:

Total distance = Distance traveled northward + Distance traveled westward

Total distance = 600 km + 100 km = 700 km

Therefore, the plane will travel a total distance of 700 kilometers in 2 hours.
