Question

Вес тела равен 2000 Н. Определите коэффициент трения, если сила трения равна 800 Н.

Answer 1

Н это ньютон ,остальное 500

Answer 2

Calculation of the Coefficient of Friction

To determine the coefficient of friction, we need to use the formula:

F = μN

Where: - F is the force of friction (800 N in this case) - μ is the coefficient of friction (what we're trying to find) - N is the normal force (equal to the weight of the object, which is 2000 N in this case)

To find the normal force, we can use the formula:

N = mg

Where: - m is the mass of the object (unknown) - g is the acceleration due to gravity (approximately 9.8 m/s^2)

Since the weight of the object is given as 2000 N, we can solve for the mass:

2000 N = mg

Simplifying the equation, we have:

m = 2000 N / g

Now we can substitute the value of mass into the equation for the coefficient of friction:

F = μN

800 N = μ * (2000 N / g)

Simplifying further, we have:

μ = (800 N * g) / 2000 N

To calculate the coefficient of friction, we need the value of g, which is approximately 9.8 m/s^2. Substituting this value into the equation, we get:

μ = (800 N * 9.8 m/s^2) / 2000 N

Calculating this expression, we find:

μ ≈ 3.92

Therefore, the coefficient of friction is approximately 3.92.
