Two particles oscillate in simple harmonic motion along a straight line segment with length $\mathrm{.}83$m$.$ Each particle has a period of $3\mathrm{.}2$ seconds but they differ in phase by pi$/7$rad. How far apart are they $\mathrm{.}81$s after the lagging particle leaves one end of the path? Your answer is partially correct.

Two particles oscillate in simple harmonic motion along a common straight$-$line segment of length $0\mathrm{.}83$ m $.$ Each particle has a period of $3\mathrm{.}2$ s $,$ but they differ in phase by $\backslash (\backslash$pi $/7\backslash$mathrm$\{$rad$\}\backslash ).($a$)$ How far apart are they $0\mathrm{.}81$ s after the lagging particle leaves one end of the path? $($b$)$ Are they then moving in the same direction, toward each other, or away from each other?
