26. ao The drawing shows three situations in which a block is attached to a spring. The position labeled “O m" represents the unstrained position of the spring. The block is moved from an initial position x, to a final position x, the magnitude of the displacement being denoted by the sym- bol s. Suppose the spring has a spring constant of k = 46.0 N/m. Using the data provided in the drawing, determine the total work done by the restoring force of the spring for each situation.
