Main cap.1
1.1 If the system shown in fig. has m= 0.010kg and s= 36 N/m , calculate (a) the angular frequency, (b) the frequency, and (c) the period.
(a) \begin{equation} F = \sqrt{s \over m} \end{equation}
\begin{equation} f= \sqrt{36 \over 0.010} = 60 {s^{-1}} \end{equation}
(b) \begin{equation} f = {1 \over 2\pi} \sqrt{s \over m} = 9.5 Hz \end{equation}
(c) \begin{equation} T= { 2\pi} \sqrt{m \over s} = 0.10 s \end{equation} --David Hernandez Leon (discusión) 22:00 4 may 2013 (CDT)

1.8 Calculate the maximum acceleration (in units of g) of pickup stylus reproducing a frequency of 16 kHz, with an amplitude of 0.01mm.
Datos:
f =16kHz = 16000Hz.
A = 0.01mm = 0.00001m.
