SUMMARY
The work needed to stretch a spring with a spring constant of k = 88 N/m from an initial displacement of x = 4.2 cm to a final displacement of x = 6.2 cm can be calculated using the area under the force versus displacement graph. The force exerted by the spring is given by Fs = kx, which results in a force of 176 J for a displacement of 2 cm. This calculation confirms that the work done is directly related to the change in displacement and the spring constant.
