When a 50 kg box is placed on a spring, the length of the spring is 20 cm as shown in the figure below (on the left). The box is then removed, and a rope is attached to the spring via a pulley, as shown on the right. When a tension of 300 N is applied to the rope, the change in length in the spring is L = 8 cm between the two scenarios. What is the equilibrium length of the spring (in cm)? 50 kg L 20 cm rope 300 N
