Answer:
Net force
I think it’s balanced force
To show stuff that we cant see in very well
The segment of the motion that net force act on the object causing a positive acceleration is segment 1.
<h3>
Motion of an object</h3>
The motion of an object occurs when a net force greater than zero acts on the object.
The force on the object is determined from Newton's second law of motion.
F(net) = ma
where;
- m is mass of the object
- a is acceleration of the object
<h3>Acceleration of the object from the graph</h3>
- Segment 1: the acceleration is positive
- Segment 2: the acceleration is zero
- Segment 3: the acceleration is negative
- Segment 4: the acceleration is zero
Thus, the segment of the motion that net force act on the object causing a positive acceleration is segment 1.

<h3>Answer</h3>
option B)
19N
<h3>Explanation</h3>
If the object is at equilibrium, then the net force acting upon the object should be 0 N. Thus, if all the forces are added together, horizontal and vertical forces separately, then the resultant force (the vector sum) should be 0 Newton.
As we only need to find the magnitude of x-component of force F (which i assume is the 4th force which makes it equilibrium)
so find all x component/horizontal forces acting on the object.
50cos(40) - 40cos(25) + 30cos(55) + x = 0
38.30 - 36.25 + 17.21 + x + = 0
19.26 + x = 0
x = - 19.26
x ≈ 19 (magnitude only)
