Suppose the bottom support in the mass-spring chain in Example 9.36 is removed.
(a) Do you predict that the vibration rate will
(i) Speed up.
(ii) Slow down, or
(iii) Stay the same?
(b) Verify your prediction by computing the new vibrational frequencies.
(c) Suppose the middle mass is displaced by a unit amount and then let go. Compute and graph the solutions in both situations. Discuss what you observe.
