The body moves evenly along the plane. the force of its pressure on the plane is 10 N, the friction force is 2.5 N. find the coefficient of sliding friction.
To find the value of the coefficient of sliding friction between a contacting plane and a uniformly moving body, we use the formula: Ftr = μ * N = μ * F whence we express: μ = Ftr / F.
Constant and variable quantities: Ftr – friction force (Ftr = 2.5 N); F is the force of pressure on the plane (F = 10 N).
Calculation: μ = Ftr / F = 2.5 / 10 = 0.25.
Answer: The coefficient of sliding friction between the contacting plane and the body is 0.25.
