Physics Teaching is my EXPERTISE with assured improvement
For a spring
F =K*X
where K = spring constant
K = F/X
= 16/0.4 = 40N/m
now F1/F2 = X1/X2
Plug in X1 and X2
X1 = X
X2 = 2X
Then X1 = X and X2 = 3X
Finally X1 = X
and X2 = X/2
Get F in each case

Actually, I do understand how you got the spring constant of 40N/m, but I just don't understand the rest of the proportions you've set up02/09/21

me neither. however, since k is constant and will always be the same. the force will depend on the distance moved. halving the distance reduces the force to pull the length by 2. multiplying by 2 causes the force to be multiplied by 2 and 3 with 3 so force will be proportionate to distance, 2x the force if 2x the distance as long as spring constant is the same.02/16/23

I don't understand, I'm sorry. What are all the x's? How is 40N/m related to this? Is that the spring constant? F1, what is force one and force two? Is that the force we are solving? How do we get displacement 2 (x2)02/09/21
