1. The problem statement, all variables and given/known data

The question ask for the spring constant if the mass is 2 kg and the Natural Friction is 5 Hz.

2. Relevant equations

3. The attempt at a solution
I have tried many different things but nothing other than putting in random spring constants into the 1/2pi*sqrt of (k/m). This came out to 1,974 N/m. I need a formula to get this awnser without guessing though.

### Snazzy

The angular frequency can be related to the spring constant and the mass and the frequency with the equation:

$$\omega = \sqrt{\frac{k}{m}} = 2\pi f$$

Thanks man, I figured it out, take that then ^2 it, then multiply by 2 and I got my awnser.
