i got a mass "m" which is stuck to a spring which is hanged from the sealing .
k-the spring coefficient
the formula for acceleration is
a=-A*w^2*sin(wt+u)
i need to calculate the force which the spring exerts of the mass in any given moment
t=0 is when he was moved downward by distance A (amplitude) to some amplitude and released.
my main question is why the phase angle "u" is pi/4 ??
