Question

1. what is the net force of the figure below? 10 n → 2 n a. net force= b. is this balanced or unbalanced? 18. what is the net force of the figure below? 2 n→ 4 n→ a. net force= b. is this balanced or unbalanced? balanced forces 19. what is the net force of the figure below? 63 n→ 100n← 37 n→ a. net force = b. is this balanced of unbalanced? 20. look at the picture below. the arrows show the direction and force of the two big horn rams. what is the net force of the rams? 64n→ 64n← a. net force= b. is this balanced or unbalanced?

Explanation:

Step1: Calculate net - force for 17

Forces act in the same direction, so add them.
$10N + 2N=12N$

Step2: Determine balance for 17

Since there is a non - zero net force, it is unbalanced.

Step3: Calculate net - force for 18

Forces act in the same direction, so add them.
$2N+4N = 6N$

Step4: Determine balance for 18

Since there is a non - zero net force, it is unbalanced.

Step5: Calculate net - force for 19

Forces act in opposite directions on the horizontal axis. Calculate horizontal net - force: $100N−63N = 37N$. Forces on the vertical axis cancel each other out ($37N$ up and $37N$ down). So the net force is $37N$.

Step6: Determine balance for 19

Since there is a non - zero net force, it is unbalanced.

Step7: Calculate net - force for 20

Forces act in opposite directions and have the same magnitude. So net force is $64N−64N=0N$.

Step8: Determine balance for 20

Since the net force is $0N$, it is balanced.
