What is the maximum acceleration of a platform that oscillates with an amplitude of 2.70 cm and at a frequency of 6.40 Hz?

2. Relevant equations

[tex]a(t)=-\omega^2x_m\cos{(\omega t=\phi)}[/tex]

[tex]\omega=2\pi f[/tex]

3. The attempt at a solution

a(t) will be maximized when a'(t)=0 (or when cosine's argument=1; it works out exactly the same).

So I want [tex]\omega t +\phi=0 or \pi[/tex]. I can shove in (2)(pi)(f) for omega no problem, but I'm stuck with the flipping phase constant. Can I just assume that it's zero??
