Question

Два автомобиля одинаковой массы m движутся дуг за другом: один со скоростью v1, другой со скоростью v2 относительно Земли. Импульс второго автомобиля в системе отсчета , связанной с первым автомобилем.

Answer 1

Два автомобиля одинаковой массы m движутся дуг за другом: один со скоростью v1, другой со скоростью v2 относительно Земли. Импульс второго автомобиля в системе отсчета , связанной с первым автомобилем.

Vотн= V1-V2
Pотн=m*(V1-V2) - ответ

Answer 2

The question is about the impulse of the second car in the reference frame of the first car. The impulse is defined as the product of mass and velocity, so we need to find the relative velocity of the second car with respect to the first car. To do this, we can use the formula:

$$v_{rel} = v_2 - v_1$$

where $v_{rel}$ is the relative velocity, $v_2$ is the velocity of the second car, and $v_1$ is the velocity of the first car. Then, the impulse of the second car in the reference frame of the first car is:

$$p = mv_{rel} = m(v_2 - v_1)$$

where $p$ is the impulse, and $m$ is the mass of the car. This is the answer to the question.
