Question

A particle, moving with simple harmonic motion, passes from rest to rest through a distance of 20cm. The periodic time is 5 sec. Find the greatest speed attained by the particle.
\[T=\frac{2\pi}{n}\]
\[n=\frac{2\pi}{5}\]
\[x''=-n^{2}x\]
\[=-\frac{4\pi^{2}}{25}x\]

Answer 1

passes from rest to rest ?

Answer 2

anyway,
\[\Huge V_{\max}=A \times \omega \]

Answer 3

I think it means it does this:
