Answer:
The coefficient of friction between the log and the ground is, μₓ = 0.3630
Explanation:
Given data,
The skidder dragging the mass, m = 520 kg
The acceleration of the mass, a = 3.5 m/s
The force applied by the skidder, Fₓ = 1850 N
The kinetic frictional force is given by,
Fₓ = μₓ η
μₓ = Fₓ / η
Where μₓ - the coefficient of the kinetic friction
η is the normal force acting on the mass due to gravitational force.
η = mg
= 520 x 9.8
= 5096 N
Substituting the values in the above equation,
μₓ = 1850 N / 5096 N
= 0.3630
Hence, the coefficient of friction between the log and the ground is, μₓ = 0.3630
