Question

масса грузового автомобиля в 6 раз больше массы легкового автомобиля . Скорость легкового автомобиля 2 раза больше , чем грузового сравните модули импульсов автомобилей .

Answer 1

импульс тела равен 

$p=m*v$

m-масса кг

v-скорость м/c

импусль грузовика равен $p=6mv$

импульс легковушки равен $p=m2v$

m-масса легковушки

v-скорость грузока

$\frac{p_{gruzovik}}{p_{legkowuschka}} = \frac{6mv}{2mv} = 3$

импульс грузовика в 3 раза больше импульса легковушки

Answer 2

Comparison of Impulses of Vehicles

To compare the impulses of a cargo truck and a passenger car, we need to consider their masses and velocities.

Given that the mass of the cargo truck is 6 times greater than the mass of the passenger car, and the velocity of the passenger car is 2 times greater than the velocity of the cargo truck, we can calculate the impulse for each vehicle.

Let's denote the mass of the passenger car as m1, the mass of the cargo truck as m2, the velocity of the passenger car as v1, and the velocity of the cargo truck as v2.

The impulse (I) of an object is given by the product of its mass and velocity:

I = m * v

For the passenger car: - Mass of the passenger car (m1) = m - Velocity of the passenger car (v1) = 2v

For the cargo truck: - Mass of the cargo truck (m2) = 6m - Velocity of the cargo truck (v2) = v

Now, let's calculate the impulses for both vehicles:

Impulse of the passenger car (I1): I1 = m1 * v1 = m * (2v) = 2mv Impulse of the cargo truck (I2): I2 = m2 * v2 = (6m) * v = 6mv Comparing the impulses, we can see that the impulse of the passenger car (I1) is equal to the impulse of the cargo truck (I2). Therefore, the modules of the impulses of the two vehicles are the same.

In conclusion, the modules of the impulses of the passenger car and the cargo truck are equal.
