Finding Parameters for Simple Harmonic Motion at t=1

Click For Summary
SUMMARY

The discussion focuses on calculating parameters for Simple Harmonic Motion (SHM) at time t=1 second, where the displacement is 1 cm, velocity is 2 cm/s, and acceleration is -3 cm/s². The key equations involved include the generic form of SHM, s=Acos(ωt+φ), and the relationships between angular frequency (ω), amplitude (A), and phase constant (φ). The solution requires substituting the known values into the equations to derive the angular frequency, amplitude, and phase constant definitively.

PREREQUISITES
  • Understanding of Simple Harmonic Motion (SHM)
  • Familiarity with trigonometric functions and their applications in physics
  • Knowledge of angular frequency (ω) and its relationship to velocity and displacement

You are not asked or told about period, so don't bother with equations involving that.
Start with a generic form of equation, s=Acos(ωt+φ). You need the φ because phase is mentioned.
In terms of A, ω and φ, what are:
- the displacement when t=1,
- the velocity when t=1
- the acceleration when t=1?
