Answer:

μ = 0.385

Explanation:

Given that,

The mass of the student, m = 69 Kg

The horizontal force applied, F = 260 N

The normal force acting on the body, weight = mg = 69g N

= 676.2 N

The coefficient of friction acting on a body is equal to the force acting on the body to the normal force acting on the body due to gravitation.

The formula for coefficient of friction,

μ = F / N

Substituting the values in the above equation,

μ = 260 N / 676.2 N

= 0.385

Hence, the coefficient of friction, μ = 0.385
