The collar has a mass of $$2\mathrm{kg}$$ and is free to slide along Part A the smooth rod, which rotates in the horizontal plane as shown in (Figure 1). The attached spring has a stiffness $$k=1\mathrm{kN}/\mathrm{m}$$, and when no force is applied to the 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 spring its unstretched length is $$d=0.5\mathrm{m}$$ rotation it is moving with a constant speed $$v=8\mathrm{m}/\mathrm{s}$$.
