(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Unstretched Spring and Angular Velocity Problem

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

A disk of mass 73 kg is held by a spring of unstretched length 88 cm and stiffness constant 430 N/cm, and rests on a frictionless table. It is then orbited in a circle at angular velocity .675 rad/s.

By how much is the spring stretched? Answer in units of cm.

2. Relevant equations

After a bit of derivation, I came up with x = r/((k/mw^2)-1).

3. The attempt at a solution

r = 88

k = 430

m= 73

w = .675

It does not seem to work out. Am I being to complicated about it? Any help/hand-holding is greatly appreciated.
