Question

Автомобиль массой 3т двигается с ускорением 2 м/с^2. Найти силу тяги двигателя, если коэффициент трения равен 0,5

Answer 1

3т=3000 кг
F=3000(2+10×0.5)=21000=21Кл

Answer 2

Calculating the Force of Engine Traction

To calculate the force of engine traction, we can use the following formula:

F = m * (a + g + μ)

Where: - F = force of engine traction - m = mass of the car (3 tons, which is equivalent to 3000 kg) - a = acceleration (2 m/s^2) - g = acceleration due to gravity (approximately 9.81 m/s^2) - μ = coefficient of friction (0.5)

Calculating the Force of Engine Traction

Using the given values: - m = 3000 kg - a = 2 m/s^2 - g = 9.81 m/s^2 - μ = 0.5

We can calculate the force of engine traction using the formula:

F = m * (a + g + μ)

Substitute the values: F = 3000 * (2 + 9.81 + 0.5)

Calculating: F ≈ 3000 * 12.31

F ≈ 36,930 N

So, the force of engine traction is approximately 36,930 Newtons.
