Answer:

Step-by-step explanation:

Hooke's Law applies here, which is a linear relationship. It would be easier to solve this using proportions with N of force on the top and the amount of stretch in cm on the bottom. Set up with our unknown, the number of cm:

[tex]\frac{N}{cm}:\frac{20}{5}=\frac{60}{x}[/tex] and cross multiply:

20x = 300 so

x = 15 cm
