Question

Скорость легкового автомобиля в 2 раза больше скорости грузового,а масса в 3 раза меньше массы грузового автомобиля.сравните модули импульсов автомобилей

Answer 1

П1=2в грузовика*м авто п2=в грузовика*0.5в авто
П1>п2( по модулю)

Answer 2

Comparison of Impulses of Cars

To compare the impulses of the two cars, we need to consider their velocities and masses. Let's assume the velocity of the passenger car is v and the velocity of the truck is v/2 (since the speed of the passenger car is twice that of the truck). Additionally, let's assume the mass of the passenger car is m and the mass of the truck is 3m (since the mass of the passenger car is three times less than the mass of the truck).

The impulse of an object is given by the product of its mass and velocity. Therefore, the impulse of the passenger car can be calculated as I1 = m * v and the impulse of the truck can be calculated as I2 = 3m * (v/2).

Let's calculate the impulses:

Impulse of the passenger car (I1) = m * v.

Impulse of the truck (I2) = 3m * (v/2).

Now, let's simplify the expressions:

I1 = mv.

I2 = (3m * v) / 2.

Therefore, the impulse of the passenger car is mv and the impulse of the truck is (3m * v) / 2.

Please note that the above calculations are based on the assumption that the velocity and mass ratios provided in the question are accurate.
