Question

Автомобиль массой 4 000 кг имеет площадь опоры колес 800 см3.Чему равно давление автомобиля на дорогу?дано,решение:

Answer 1

P=FS, где F сила тяжести ,S площадь опоры.

P=mg*S=4000*10/0,008=5000000Па

Answer 2

Calculation of the Pressure of the Car on the Road

To calculate the pressure of the car on the road, we need to use the formula:

Pressure = Force / Area

In this case, the force is the weight of the car, and the area is the contact area of the wheels with the road.

Given: - Mass of the car = 4,000 kg - Area of wheel contact = 800 cm^2

To calculate the force, we can use the formula:

Force = Mass x Acceleration due to gravity

The acceleration due to gravity is approximately 9.8 m/s^2.

Let's calculate the force first:

Force = 4,000 kg x 9.8 m/s^2

Using this force, we can calculate the pressure:

Pressure = Force / Area

Now, let's substitute the values and calculate the pressure.
