What is the phase constant? (Figure 1) is the position-versus-time graph of a particle in simple harmonic motion. \[ \begin{array}{l} \phi_{0}=-\frac{\pi}{3} \mathrm{rad} \\ \phi_{0}=\frac{\pi}{3} \mathrm{rad} \\ \phi_{0}=-\frac{2 \pi}{3} \mathrm{rad} \\ \phi_{0}=\frac{2 \pi}{3} \mathrm{rad} \end{array} \] Part B What is the velocity at \( t=0 \) s? Express your answer to two significant figures and include the appropriate units. Figure 1 of 1 Part C What is \( v_{\max } \) ? Express your answer to two significant figures and include the appropriate units.
