The position versus time equation is:

$\overline{){\mathbf{x}}{\mathbf{\left(}}{\mathbf{t}}{\mathbf{\right)}}{\mathbf{=}}{\mathbf{A}}{\mathbf{c}}{\mathbf{o}}{\mathbf{s}}{\mathbf{(}}{\mathbf{\omega}}{\mathbf{t}}{\mathbf{+}}{{\mathbf{\varphi}}}_{{\mathbf{0}}}{\mathbf{)}}}$

The angular frequency:

$\overline{){\mathbf{\omega}}{\mathbf{=}}\frac{\mathbf{2}\mathbf{\pi}}{\mathbf{T}}}$

**A)**

Amplitude is the maximum change in the wave's position.

(Figure 1) shows a position-versus-time graph for a particle in SHM.

A) What is the amplitude A?

B) What is the angular frequency *ω*?

C) What is the phase constant *ϕ*_{0}?
