An object of mass M is attached to a spring with spring constant k whose unstretched length is L, and whose far
end is fixed to a shaft that is rotating with angular speed omega. Neglect gravity and assume that the mass rotates with angular speed omega as shown. (Intro 1 figure) When solving this problem use an inertial coordinate system, as drawn here. (Intro 2 figure)
(a)The object is attachedto spring. Here, the centripetal force is equal to
the tangential force. a =5:
19!sz = k[R-L)
Solve the equation for R.
