The drawing shows three situtations in which a block is attached to a spring. The positionis labeled "0 m" represents the unstrained position of the spring. The block is moved from an intital position x0 to a final position xf, the magnitude of the displacement being denoted by the symbol s. Suppose the spring has a spring constant of k=78 N/m. Using the data provided in the drawing, determine the total work done by the restoring force of the spring of each situation. In the case of zero put your result as "+0"
