To find: The amplitude of model

Answer to Problem 79E
Explanation of Solution
Given: A weight is attached to a spring suspended vertically from a ceiling. When a driving force is applied to the system, the weight moves vertically from its equilibrium position, and this motion is modeled by
The simplified model of spring,
The coefficient of trigonometry function is amplitude of the wave.
Hence, the amplitude is
To find: The frequency of the oscillations of the weight.

Answer to Problem 79E
2
Explanation of Solution
Given: A weight is attached to a spring suspended vertically from a ceiling. When a driving force is applied to the system, the weight moves vertically from its equilibrium position, and this motion is modeled by
The model of oscillation of weight,
The coefficient of t is frequency of wave.
Hence, the frequency of wave is 2.
