Question

На санки мостом 8 кг скользящие по горизонталь ной дороге, действуют сила трения 8. Определите коэффициент трения между полями и дорогой

Answer 1

M=8 кг                     μ=F/mg;
g=10 м/с²                 μ=8/8*10=0,1.
F=8 H
μ=?

Answer 2

Calculating the Coefficient of Friction

To calculate the coefficient of friction between the sled and the road, we can use the formula:

Frictional force (F) = Coefficient of friction (μ) × Normal force (N)

Given: - Mass of the sled (m) = 8 kg - Frictional force (F) = 8 N

We can calculate the normal force (N) using the formula: N = m × g where: - m = mass of the sled - g = acceleration due to gravity (approximately 9.81 m/s^2)

Let's calculate the normal force (N): N = 8 kg × 9.81 m/s^2

Now, we can use the calculated normal force and the given frictional force to find the coefficient of friction (μ): F = μ × N

Calculation

Using the given values and the formulas mentioned above: - Normal force (N) = 8 kg × 9.81 m/s^2 - Frictional force (F) = 8 N

We can now calculate the coefficient of friction (μ) using the formula: μ = F / N

Result

By substituting the calculated values into the formula, we get: μ = 8 N / (8 kg × 9.81 m/s^2)

Final Calculation

Let's calculate the coefficient of friction (μ): μ ≈ 8 N / 78.48 N ≈ 0.102

So, the coefficient of friction between the sled and the road is approximately 0.102.
