SUMMARY
The discussion centers on calculating the horizontal component of force for a system involving two blocks with different masses. The equation presented, \(\Sigma F_{x_1} = F_a - (f_k + N_2) = ma\), is used to analyze the forces acting on the blocks. The user attempts to find the normal force and friction but arrives at an incorrect value of 6.877 N. The correct approach involves calculating the gravitational force on the 0.4 kg object to determine the necessary upward friction and subsequently finding the normal force exerted by the 1.8 kg object.
