Question

an initial amplitude k, damping constant c, and fequency f are given. k=3, c=3.5, and f=4. find a function that models the damped harmonic motion.use a function y=ke^(-ct)cos wt

Answer 1

I cant read that^

Answer 2

Its very clear...

Answer 3

sure it is if your wearing cheap glasses like you may be^

Answer 4

ok its gone

Answer 5

\[f=\frac{ 1 }{ T }\]

Answer 6

\[4=1/T\]
\[t=1/4\]
this is t \[w=\frac{ 2\pi }{ T }\]

Answer 7

\[wt=2\pi\]
\[y=3e^{(-3.5*1/4)}\cos 2\pi\]
