Question

Simple Harmonic Motion

Answer 1

\[x=2.10\sin(17.59t)\] \[V_{\max}= Aw \rightarrow (2.10)(17.59)= 36.9 1 ~cm/s\]\[\frac{ dx }{ dt }= v(t)= (2.10*17.59)\cos(17.59t)\]
\[36.9 =36.9 \cos(17.59t) ~~~~\rightarrow \cos(17.59t)=1 ~~~\rightarrow 17.59t =\cos^{-1}(1) ~~~\rightarrow t=0???!?\]

Answer 2

*this speed* = v.max= 36.9 cm/s
