A spring stretches by 0.0167 rn when a 4.38kg object is suspended from its end. How much mass should be attached to this spring so that its frequency of vibration is f= 3.00 Hz? 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 xo to a final position *, the magnitude of the displacement being denoted by the symbol s. Suppose the spring has a spring constant of k = 68.0 N/m. Using the data provided in the drawing, determine the total work done by the restoring force of the spring for each situation. In the case of zero put your result as "+0".
