Chapter 5 Review Questions How would you calculate the spring constant of an unknown spring?
A. graph the force vs. extension of the spring and find the slope
B. Use Hooke's law to calculate the spring constant knowing one force of the spring and one deformation of the spring
C. graph the force vs. extension of the spring and find the inverse of the slope
D. conduct a series of experiments with different amounts of deformation on the spring and calculate spring constant with Hooke's Law
