The collar has a mass of 2 kg and is free to slide along the smooth rod, which rotates in the horizontal plane. The attached spring has a stiffness k = 1 kN/m, and when no force is applied to the spring its unstretched length is d = 0.5 m. Determine the force which the spring exerts on the collar when the collar is at rest with respect to the rod, yet due to the rod’s rotation it is moving with a constant speed v = 6 ms.
