The natural frequency of vibration of a person is found to be 5.2 Hz while standing on a horizontal floor. Assuming damping to be negligible, determine the vertical displacement of the person at time = 0.5s when the floor is subjected to a vertical harmonic vibration of frequency 5.3 Hz and amplitude 0.009m. Assume the mass of the person to be 73kg. Answer in m with 3 decimal places.

Two different simple harmonic oscillators have the same natural frequency (f=2.00 Hz) when they are on the surface of the Earth. The first oscillator is a pendulum, the second is a vertical spring and mass. If both systems are moved to the surface of the moon (g=1.67 m/s2), what is the new frequency of the vertical spring and mass?

(1A) A vertical spring with a spring constant of 8 N/m and damping constant of 0.05 kg/s has a 2 kg mass suspended from it. A harmonic driving force given by F = 2 cos(1.5 t ) is applied to the mass. What is the natural angular frequency of oscillation of the mass? What is the amplitude of the oscillations at steady state? Does this amplitude decrease with time due to the damping? Why or why not?

You can sometimes hear a low-frequency “moaning” noise when strong winds blow through power lines strung between two poles. The wind is exciting a particular standing wave mode on the wire between its fixed ends at the poles; in this example, the wire is observed to have the shape shown in the diagram below at a particular instant in time. (a) If, for this mode (or harmonic), the frequency you hear is 20 Hz (near the lower threshold of human...
