Answer:
The spring constant is ![k =1000 \ N/m](https://tex.z-dn.net/?f=k%20%20%3D1000%20%5C%20N%2Fm)
Step-by-step explanation:
From the question we are told that
The resting length is
The extension of spring is ![e = 0.02 \ m](https://tex.z-dn.net/?f=e%20%3D%20%200.02%20%5C%20m)
The new length of spring is ![l = 0.10 \ m](https://tex.z-dn.net/?f=l%20%3D%20%200.10%20%5C%20m)
The force is ![F = 20 \ N](https://tex.z-dn.net/?f=F%20%3D%20%2020%20%5C%20N)
The spring constant is
![k = \frac{F}{e}](https://tex.z-dn.net/?f=k%20%20%3D%20%5Cfrac%7BF%7D%7Be%7D)
substituting values
![k = \frac{20}{0.02}](https://tex.z-dn.net/?f=k%20%20%3D%20%5Cfrac%7B20%7D%7B0.02%7D)
![k =1000 \ N/m](https://tex.z-dn.net/?f=k%20%20%3D1000%20%5C%20N%2Fm)
Answer:
A. $14.40 B. 12.80 C. 22.5
Step-by-step explanation:
It depends what the x is, lets say it is $16, then the discount price will be $20
