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 length d if 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 m/s.
