Question

Какая сила трения действует на тело массой 50кг,если коэффициент трения равен 0,2?

Answer 1

Дано:
m = 50 кг
μ = 0,2

Сила трения:
F = μ*m*g = 0,2*50*10 = 100 H

Ответ: Сила трения равна 100 ньютонов

Answer 2

Calculating Frictional Force

To calculate the frictional force acting on a body with a mass of 50 kg and a coefficient of friction of 0.2, we can use the formula:

F = μN

Where: - F is the frictional force - μ is the coefficient of friction - N is the normal force

The normal force (N) can be calculated using the formula N = mg, where: - m is the mass of the object (50 kg) - g is the acceleration due to gravity (approximately 9.81 m/s^2)

Substituting the values, we get: N = 50 kg * 9.81 m/s^2

Now, we can calculate the frictional force using the formula F = μN, where: - μ is the coefficient of friction (0.2) - N is the normal force we just calculated

Let's calculate the normal force and then the frictional force.
