Answer:
The spring constant is [tex]k =1000 \ N/m[/tex]
Step-by-step explanation:
From the question we are told that
The resting length is [tex]x = 0.08 \ m[/tex]
The extension of spring is [tex]e = 0.02 \ m[/tex]
The new length of spring is [tex]l = 0.10 \ m[/tex]
The force is [tex]F = 20 \ N[/tex]
The spring constant is
[tex]k = \frac{F}{e}[/tex]
substituting values
[tex]k = \frac{20}{0.02}[/tex]
[tex]k =1000 \ N/m[/tex]
