Newton's Law of motion Grade 11. Question 5, Nov. 2023 Gauteng Province, South Africa.

In this video I am going to not just solve a question on Newton's Law of motion but i am going to explain some important concepts related the question.
This was question 5 done in the November question paper in 2023 in the Gauteng Province in South Africa.
It is a question related to Newton's Law of motion where two object moves on an incline surface.
Definitions:
Free-body diagrams: is a diagram that shows the relative magnitudes and
directions of forces acting on a body/particle that has been isolated from its
surroundings. (no components accepted).
Newton's first law of motion: A body will remain in its state of rest or motion at constant velocity unless a non-zero resultant/net force acts on it.
Newton's second law of motion: When a net force acts on an object, the object will accelerate in the direction of the force and the acceleration is directly proportional to the force and inversely proportional to the mass of the object.
Newton's third law of motion: When object A exerts a force on object B, object B SIMULTANEOUSLY exerts an oppositely directed force of equal magnitude on object A.

Examples of Action-Reaction pair for this question could be:
1 - Force that block A exert on block B and the force that block B exert on block A.
2 - From the blocks exert on the the surface (fk) and the force the surface exert on the blocks.
