The position labeled "0 m" represents the unstrained position of the spring.

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 displacement is s. Suppose the spring constant is 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.
