The value of the spring constant of the spring is 14.7 N/m.
The given parameters;
- <em>mass attached to the spring, m = 30 g</em>
- <em>length of the spring, L₀ = 10 cm</em>
- <em>angular speed of the mass = 90 rpm</em>
- <em>final length of the spring, L₁ = 12 cm</em>
The extension of the spring is calculated as follows;
![\Delta x = L_1 - L_0\\\\\Delta x = 12 \ cm - \ 10 \ cm\\\\\Delta x = 2 \ cm = 0.02 \ m](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%20L_1%20-%20L_0%5C%5C%5C%5C%5CDelta%20x%20%3D%2012%20%5C%20cm%20-%20%5C%2010%20%5C%20cm%5C%5C%5C%5C%5CDelta%20x%20%3D%202%20%5C%20cm%20%3D%200.02%20%20%5C%20m)
The value of the spring constant of the spring is calculated by applying Hooke's law;
![F = mg = k\Delta x\\\\k = \frac{mg}{\Delta x } \\\\k = \frac{0.03 \times 9.8}{0.02} \\\\k = 14.7 \ N/m](https://tex.z-dn.net/?f=F%20%3D%20mg%20%3D%20k%5CDelta%20x%5C%5C%5C%5Ck%20%3D%20%5Cfrac%7Bmg%7D%7B%5CDelta%20x%20%7D%20%5C%5C%5C%5Ck%20%3D%20%5Cfrac%7B0.03%20%5Ctimes%209.8%7D%7B0.02%7D%20%5C%5C%5C%5Ck%20%3D%2014.7%20%5C%20N%2Fm)
