Question

Масса грузового автомобиля в 6 раз больше массы легкового автомобиля.Скорость легкового автомобиля в 1 1/3 раза выше,чем грузового.сравните модули импульсов автомобилей.

Answer 1

M=6m
4/3*V=v
(M*V)/(m*v)=(6m*V)/(m*V*4)/3=(6*3)/4=18/4=9/2

Answer 2

Comparing Impulses of Vehicles

To compare the impulses of the two vehicles, we can use the formula for impulse, which is given by the product of force and time. The impulse experienced by an object is equal to the change in momentum of the object. The impulse experienced by each vehicle can be calculated using the following formula:

Impulse = Force × Time

First, let's calculate the impulse for the two vehicles.

1. Impulse of the Light Vehicle (Car): - Given that the speed of the light vehicle is 1 1/3 times higher than the heavy vehicle, we can assume that the force and time are the same for both vehicles. Therefore, the impulse for the light vehicle can be represented as I_car = F_car × t_car.

2. Impulse of the Heavy Vehicle (Truck): - Since the mass of the truck is 6 times greater than the mass of the car, the force experienced by the truck will be 6 times greater than the force experienced by the car. Therefore, the impulse for the heavy vehicle can be represented as I_truck = 6F_car × t_truck.

Now, let's compare the modules of the impulses of the two vehicles.

The module of an impulse is the absolute value of the impulse, which represents the magnitude of the change in momentum.

3. Comparing the Modules of Impulses: - The module of the impulse for the car can be represented as |I_car| = |F_car × t_car|. - The module of the impulse for the truck can be represented as |I_truck| = |6F_car × t_truck|.

By comparing the modules of the impulses, we can determine the relative magnitude of the change in momentum experienced by each vehicle.

Let's calculate the specific values for the impulses and compare their modules.
