Consider the graph for an expandable spring below a) What is the elasticity constant of this spring? b) What is the energy stored when the spring is stretched from 200mm to 400mm? c) How does the amount of energy stored when the spring is stretched from 400mm to 600mm compare to that in the previous question? Use the graph to justify your answer. Force (N) 1 0 0 100 200 300 400 500 800 700 800 Spring Length (mm)
