SUMMARY
The equation of motion for simple harmonic motion (SHM) of a mass on a spring is defined as y = A cos(ωt), where A represents the amplitude and ω is the angular frequency. For the scenarios presented: (a) when released 10 cm above the equilibrium position, the equation is y = 0.10 cos(t/√(m/k)); (b) for an upward push resulting in an 8 cm maximum displacement, the amplitude A is 0.08; (c) for a downward push with a 12 cm maximum displacement, the amplitude A is 0.12. The angular frequency ω can be expressed as 2π/T, where T is the period of oscillation.
