Chapter 10, Problem 26 GO 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 x? to a final position x?, the magnitude of the displacement being denoted by the symbol s. Suppose the spring has a spring constant of k = 54 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". (a) Position of box when spring is unstrained -3.00 m 0 m +1.00 m +3.00 m (b) -3.00 m 0 m +1.00 m (c) -3.00 m 0 m +3.00 m (a) W = (b) W = (c) W =

Step 1
We can calculate the work done by the spring using the formula: \[ W = \frac{1}{2}k(x_f^2 - x_i^2) \] Substitute the values: \[ W = \frac{1}{2} \times 54 \times ((-3)^2 - 1^2) \] Show more…
