Question

Скутер проехал на север 40 км, затем повернул на запад и проехал ещё 30 км. Найти путь и перемещение скутера за всё время его движения. S1 = 40 км S2 = 30 км Путь S я узнала сложив S1+S2 и получилось 70 км Как найти модуль перемещения? (r)

Answer 1

По теореме Пифагора. 40^2+30^2=корень из 2500 или = 50. Перемещение = 50км

Answer 2

Calculating the Path and Displacement of the Scooter

To calculate the path and displacement of the scooter, we can use the given distances traveled in different directions.

The scooter first traveled 40 km to the north, and then turned to the west and traveled an additional 30 km.

Calculating the Path

To find the total path traveled by the scooter, we can simply add the distances traveled in each direction: - Distance to the north (S1) = 40 km - Distance to the west (S2) = 30 km - Total path (S) = S1 + S2 = 40 km + 30 km = 70 km

The total path traveled by the scooter is 70 km.

Calculating the Displacement

To find the displacement, we need to calculate the straight-line distance from the starting point to the ending point of the scooter's journey.

Using the Pythagorean theorem, the displacement (r) can be calculated as: - r = √(S1^2 + S2^2) - r = √(40^2 + 30^2) - r = √(1600 + 900) - r = √2500 - r = 50 km

The displacement of the scooter is 50 km.

Therefore, the modulus of the displacement of the scooter for the entire duration of its movement is 50 km.
