The drawing shows three situations in which a block is attached to a spring. the position labeled "0 m" represents the unstrained position of the spring. the block is moved from an initial 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 = 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.
