Final answer:
The dynamic coefficient of friction (μ) can be calculated using the formula μ = Fy/Fz, considering Fy as the anterior/posterior and Fz as the vertical force components. So, the correct option is A.
Step-by-step explanation:
The dynamic coefficient of friction (μ) can be calculated using the formula μ = Fy/Fz, considering Fy as the anterior/posterior and Fz as the vertical force components.
For example, if you have a force Fy of 10 N and a force Fz of 20 N, the coefficient of friction would be μ = 10 N/20 N = 0.5.
Therefore, the correct formula to calculate the dynamic coefficient of friction is a) μ = Fy/Fz.
