An object of mass M= 2.00 kg. is attached to a spring with springconstant k= 198 N/m whose unstretched length is L= 0.200 m., andwhose far end is fixed to a shaft that is rotating with an angularspeed of

ω = 3.00 radians/s . Neglect gravity and assume that the mass alsorotates with an angular speed of 3.00 radians/s as shown. (Intro 1figure)


When solving this problem use an inertial coordinate system, asdrawn here. (Intro 2 figure)


Given the angular speed of ω = 3.00 radians/s , find the radiusR(ω) at which the mass rotates without moving toward or awayfrom the origin.

Express your answer in meters.
