A force of magnitude 9.00 N pushes three boxes with masses m1 = 1.30 kg, m2 = 2.80 kg, and m3 = 4.90 kg
Find the magnitude of the contact force between boxes 1 and 2.

I thought that it would be 9.00 N, since the boxes are back-to-back-to-back, but that answer is wrong.
The magnitude of contact force between two boxes can be calculated by using the formula F = μN, where F is the contact force, μ is the coefficient of friction, and N is the normal force. The normal force can be calculated by multiplying the mass of the box by the acceleration due to gravity (9.8 m/s²). In order to calculate the coefficient of friction, you will need to know the types of surfaces in contact and their respective coefficients of friction.
The normal force is the force exerted by a surface on an object that is in contact with it. In the context of calculating contact force between two boxes, it refers to the force exerted by one box on the other due to their weight.
The coefficient of friction is a measure of the resistance between two surfaces in contact. It determines the amount of force required to overcome the friction between the two surfaces. As the coefficient of friction increases, so does the magnitude of contact force between the two boxes.
There are several factors that can affect the accuracy of the calculation for contact force between two boxes. These include the accuracy of the measurements (e.g. mass, coefficient of friction), the condition of the surfaces in contact (e.g. roughness, cleanliness), and external forces such as air resistance or vibrations.
Yes, the calculation for contact force can be applied to any objects in contact as long as the necessary information, such as the mass, coefficient of friction, and normal force, is known. It is a fundamental principle in physics and can be used to understand the behavior of various objects in contact with one another.
