Final answer:
The coefficient of friction is calculated by dividing the frictional force (125 N) by the normal force (500 N), resulting in a coefficient of 0.25.
Step-by-step explanation:
To find the coefficient of friction, we use the relationship between the frictional force, the normal force, and the coefficient of friction. This relationship is given by the equation f = μN, where f is the frictional force, μ is the coefficient of friction, and N is the normal force. In this case, the frictional force is 125 N and the normal force is 500 N.
The coefficient of friction (μ) is calculated by dividing the frictional force by the normal force, which can be expressed as μ = f/N. So, μ = 125 N / 500 N = 0.25. As coefficients of friction are approximate, this answer is given to two significant digits.
