A $33\mathrm{.}0\mathrm{????}\mathrm{????}$ long spring is hung vertically from a ceiling and stretches to $38\mathrm{.}3\mathrm{????}\mathrm{????}$ when a $7\mathrm{.}00\mathrm{????}\mathrm{????}$ mass is hung from its free end.

$($a$)$ Find the spring constant $($in $\frac{\mathrm{????}}{\mathrm{????}}).$

$($b$)$ Find the length of the spring $($in $\mathrm{????}\mathrm{????})$ if the $7\mathrm{.}00\mathrm{????}\mathrm{????}$ weight is replaced with a $215\mathrm{????}$ weight.
