we must apply a force of magnitude 83.0 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 +6.0 J of work on the spring–block system; the block is then again stationary. What are the block's positions, in cm? ((a) positive and (b) negative)
