Question

How I can Construct a graph of Stretching Force vs Spring Extension, the Force needs to be in the vertical axis. And how I can using the trendline of the graph to find the Spring Constant (aka Elastic Constant) k k = 6 ,and to find the mass of the unknown masses in the simulation using the trendline equation. Which is unknown masses that give a detailed procedure to find its mass ?

Stretching Force    mg (N)	Spring extension      y (m)
50/1000*9.8=0.49	7/100=0.07
1.08	0.13
1.67	0.19
1.96	0.23
2.35	0.27
2.74	0.31

Answer 1

Here is the graph of force vs extension.

The slope of graph will be equal to spring constant of the given spring

_____________

so,

spring constant = 9.264 N/m

______________________________________________

How you can find unknown mass ?

Just hang the unknown mass from the same spring ( for which you know the spring constant)

let the mass come to rest, measure the extension of spring

then

F = kx

mg = kx

m = kx / g

where 'x' is extension of spring,
