Question

Две силы 13 Н и 7 Н приложены к одному телу. Угол между направлениями сил равен 0 градусов Определите модуль равнодействующей силы.

Answer 1

Ответ:

угол 0, значит в одном направлении, модуль |13+7|=20 Н

Answer 2

Calculation of Resultant Force

To determine the magnitude of the resultant force when two forces of 13 N and 7 N are applied to the same object at an angle of 0 degrees between their directions, we can use the concept of vector addition.

The resultant force can be calculated using the formula:

Resultant Force = √(F1^2 + F2^2 + 2F1F2cosθ)

Where: - F1 and F2 are the magnitudes of the two forces (13 N and 7 N, respectively). - θ is the angle between the directions of the forces (0 degrees in this case).

Plugging in the values, we get:

Resultant Force = √(13^2 + 7^2 + 2 * 13 * 7 * cos(0°))

Simplifying the equation:

Resultant Force = √(169 + 49 + 182) = √400 = 20 N

Therefore, the magnitude of the resultant force is 20 N.
