SUMMARY
The discussion focuses on calculating the normal force between two moving crates with masses of 49 kg and 29 kg, subjected to a coefficient of kinetic friction of 0.30. The crates are pushed along the floor at a constant velocity, which implies that the net force acting on them is zero. The equations used include the frictional force formula Ff = μkFN, leading to the conclusion that the normal forces acting on each crate (FN1 and FN2) are both 11.7 kg.
