Homework Statement
I need to find the speed, at time t=0.015s, of a hydraulic valve component undergoing sinusoidal vibrations. The frequency of the vibrations is 25Hz, the amplitude is 2cm and the angular frequency is 157 s-1
Homework Equations
The equation for speed of sinusoidal vibrations I have is
vx(t)=Aw sin(wt+[tex]\phi[/tex]+pi/2)
The Attempt at a Solution
So far the values I have are
vx(t)=(0.02*157)*sin(157*0.015)+?+pi/2)
But I can't find anywhere how you're supposed to calculate the phase constant
