Step 1

According to Newton's second law, the acceleration is given by the force divided by the mass. In this case, the total force is $4500 \mathrm{N}$ and the total mass is the sum of the mass of the car and the truck, which is $1000 \mathrm{kg} + 2000 \mathrm{kg} = Show more…

Key Concepts

Newton's Second Law of Motion

This principle establishes that the net force acting on an object is equal to the mass of the object multiplied by its acceleration. In problems involving multiple bodies being accelerated by an applied force, the total mass of the system is considered to determine the overall acceleration, which in turn is used to calculate individual forces acting on each body.

Newton's Third Law of Motion

This law states that for every action there is an equal and opposite reaction. When two objects interact, the force exerted by the first object on the second is exactly matched in magnitude by the force exerted by the second object on the first, though in the opposite direction. This concept is crucial for understanding how forces are transmitted between interacting bodies.
