Question about phase shift SHM
The displacement of an object is given by
[tex]x(t)=x_mcos(\omega t+\phi)[/tex]
If the inital displacement is 0 and the initial v is in the negative x direction, then the phase constant must be ___rads
I know that if x=o then the cosine of the phase must be 0
[tex]\cos(\omega t+\phi)=0[/tex]
so[tex]\omega t+\phi=\frac{\pi}{2}[/tex]
and I am stuck from here...hints?
