make up two of your own net - force problems.

Explanation:

Step1: Analyze vertical forces in problem 1

For the first problem, the upward force is $F_{up}=22N$ and the downward force is $F_{down}=22N$. The net - force in the vertical direction $F_{net1}=F_{up}-F_{down}=22 - 22=0N$. The object will not move vertically.

Step2: Analyze horizontal forces in problem 2

In the second problem, the left - hand side force is $F_{left}=35N$ and the right - hand side force is $F_{right}=25N$. The net force $F_{net2}=F_{left}-F_{right}=35 - 25 = 10N$ to the left.

Step3: Analyze forces in problem 3

In the third problem, resolve the two angled forces into horizontal and vertical components. But if we consider the net force in the direction of the forces' resultant, the two forces are $F_1 = 60N$ and $F_2=50N$. The net force $F_{net3}=60 + 50=110N$ in the direction of the combined forces.

Step4: Analyze vertical forces in problem 4

In the fourth problem, the left - hand side downward force is $F_{down1}=45N$ and the right - hand side downward force is $F_{down2}=75N$. The net force $F_{net4}=F_{down2}-F_{down1}=75 - 45 = 30N$ downward.

Step5: Analyze horizontal forces in problem 5

In the fifth problem, the left - hand side force is $F_{left}=80N$ and the right - hand side forces' horizontal component (assuming the angled forces' horizontal and vertical resolution) gives a total right - hand side horizontal force of $F_{right}=80 + 20=100N$. The net force $F_{net5}=F_{right}-F_{left}=100 - 80=20N$ to the right.

Step6: Analyze horizontal forces in problem 6

In the sixth problem, the left - hand side force is $F_{left}=25N$ and the right - hand side force is $F_{right}=45N$. The net force $F_{net6}=F_{right}-F_{left}=45 - 25 = 20N$ to the right.

Answer:

1. Net force: $0N$, no movement.
2. Net force: $10N$ to the left.
3. Net force: $110N$ in the direction of the combined forces.
4. Net force: $30N$ downward.
5. Net force: $20N$ to the right.
6. Net force: $20N$ to the right.
