Question

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

Answer 1

закон сохранения импульса m1v1=m2v2

масса грузового автомобиля m1

скорость грузового автомобиля v1

масса легкового автомобиля m2

скорость легкового автомобиля v2

составим систему уравнений:

 m1=6m2

2v1=v2

     6*m*2*v1 6

     _______     __

x=m2*2*v1= 2=3

Ответ: (m1v1)/(m2v2)=3 импульс грузового авто. больше в 3 раза,чем у легкогова авто.

 

Answer 2

Comparison of Impulses of the Vehicles

To compare the impulses of the vehicles, we need to consider their masses and velocities. Let's analyze the given information step by step.

1. The mass of the cargo truck is 6 times greater than the mass of the passenger car. 2. The mass of the passenger car is 2 times greater than the mass of the cargo truck.

Based on these statements, we can set up equations to represent the relationship between the masses of the vehicles:

Let's assume the mass of the passenger car is m. Then the mass of the cargo truck would be 6m.

Now, let's compare the modules of the impulses of the vehicles. The impulse of an object is given by the product of its mass and velocity.

To compare the impulses, we need to compare the products of mass and velocity for each vehicle.

Let's assume the velocity of the passenger car is v. Then the velocity of the cargo truck would be v/2.

Now, we can calculate the impulses for each vehicle:

1. Impulse of the passenger car: m * v 2. Impulse of the cargo truck: 6m * (v/2)

To compare the modules of the impulses, we need to consider the absolute values of the calculated values.

Therefore, the comparison of the modules of the impulses of the vehicles is as follows:

|Impulse of the passenger car| = |m * v|

|Impulse of the cargo truck| = |6m * (v/2)|

Please note that the actual values of the masses and velocities are not provided in the question. Therefore, we cannot calculate the exact values of the impulses. However, we can compare the expressions for the impulses based on the given information.
