The traction force of the car is 1000 N, and the force of resistance to its movement is 700 N. What is the equal action of these forces.
Fthrust = 1000 Newton – thrust force;
Fresistance = 700 Newton – the force of resistance to motion.
It is required to determine the resultant forces F (Newton).
Let’s introduce a coordinate system where the OX axis is directed along the movement of the car. Then the traction force will be directed in the positive direction (it “pulls” the car forward), and the resistance force in the negative direction (it interferes with the movement and slows it down). Then, with this in mind:
F = Fthrust – Fresistance = 1000 – 700 = 300 Newtons.
Answer: the resultant forces will be equal to 300 Newtons.
