(b) For a spring whose equilibrium position is at x = 0 cm, we must apply a force of magnitude 80 N to hold the block stationary at x = -2.0 cm. From that position, we then slowly move the block so that our force does +4.0 J of work on the spring - block system; the block is then again stationary. What is the block's position? (Hint: There are two answers.)
