I don't undertand how to do this problem
Thanks

Newton's Laws of Motion are a set of three physical laws that describe the relationship between an object and the forces acting upon it. They were developed by Sir Isaac Newton in the late 17th century and are considered the foundation of classical mechanics.
The first law of motion, also known as the Law of Inertia, states that an object at rest will remain at rest and an object in motion will continue moving in a straight line at a constant speed unless acted upon by an external force.
The normal force is the force exerted by a surface on an object in contact with it, and it acts perpendicular to the surface. To find the normal force using Newton's Laws, you would need to first identify all the forces acting on the object and then use the second law of motion, F=ma, to calculate the normal force.
The normal force and weight are two equal and opposite forces that act on an object in contact with a surface. The normal force acts upwards and balances the weight of the object, which acts downwards due to gravity. When an object is at rest on a surface, the normal force is equal in magnitude to the weight of the object.
No, the normal force cannot be negative. It is always a positive value, as it represents the force exerted by a surface to prevent an object from passing through it. If the normal force were to become negative, it would mean that the surface is pulling the object towards it, which is not possible.
