The 13-kg sphere C is released from rest when θ = 0∘ and the tension in the spring is F = 100 N. The figure shows rod AB hinged at point A. Sphere C is attached to the other end of the rod, labeled as B. Point D is located on the rod, 0.3 meters from point A and 0.15 meters from the center of the sphere. A spring with stiffness k of 500 newtons per meter is attached to the rod at point D by one of its ends. Another end of the spring is fixed at point E, located 0.4 directly above point A.
