An object of mass = 2.00 kg is attached to a spring with spring constant k = 88.0 N/m whose unstretched length is l = 0.150 m and whose far end is fixed to a shaft that is rotating with an angular speed of w = 2.00 radians/s. the mass also rotates with an angular speed of 2.00 radians/s.
Given the angular speed of W = 2.00 radians/s find the radius R (w) at which the mass rotates without moving toward or away from the origin.
