The body is simultaneously acted upon by two forces F1 and F2, the moduli of which are 4H and 6H

The body is simultaneously acted upon by two forces F1 and F2, the moduli of which are 4H and 6H, respectively. The F1 force is directed to the right and the F2 force is directed to the left. What is the equal of the acting force of these forces? In what direction will the body move from a state of rest?

Let us introduce a coordinate system, the OX axis of which will be directed from left to right. Then, the force F2 will have a negative value (it is directed to the left), and the force F1 will have a positive value (it is directed to the right). The resulting force will be equal to:

F = F1 – F2 = 4 – 6 = -2 Newtons.

Since the resultant of the forces has a negative value, then from the state of rest the body will move to the negative side of the coordinate system, that is, to the left (in the direction of the force F2).

The movement of this body cannot be considered uniform, since the resultant of the forces is not equal to zero, which means that the body will move with some acceleration, that is, the movement will be uniformly accelerated.
