[SOLVED] Unstretched Spring and Angular Velocity Problem
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.
After a bit of derivation, I came up with x = r/((k/mw^2)-1).
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.
