Find Spring Constant/ m, and Friction known

[Jerm2006]

Homework Statement

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

Homework Equations

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.
