Consider two masses (of mass m, and m2) attached to a spring (of unstretched length / and spring constant k) in a manner similar to that discussed in this section. however, suppose the system is aligned vertically (rather than hori- zontally) and that consequently a constant gravitational force is present. analyze this system and compare the results to those of this section.
