A damped harmonic motion starts from rest at time t=0 with displacement A0 has the equation:
x(t) = A0/cos (delta)*e^(-t/tau) *cos (w't + delta)
w' is the angular frequency, tau is the time constant and delta is given by:
tan (delta) = - (1/w' tau)
find the time when the maximum negative displacement occurs. express it in terms of period.
So, Can you just give me a hint on where to start and where to go from there.
Thank you
