SUMMARY
The forum discussion centers on calculating the coefficient of kinetic friction (μk) for a box being pushed across a floor. Given a horizontal force of 28N and a box mass of 10.2 kg, the normal force (FN) is determined to be 100N. The kinetic friction force (Ffk) is equal to -28N, leading to a calculated μk of -0.28. The correct value for μk is 0.28, as the coefficient of friction is always expressed as a positive value.
