Current Attempt in Progress

An oscillating block$-$spring system has a mechanical energy of $3\mathrm{.}79$ J $,$ an amplitude of $9\mathrm{.}14$ cm $,$ and a maximum speed of $1\mathrm{.}35\backslash (\backslash$mathrm$\{$m$\}/\backslash$mathrm$\{$s$\}\backslash ).$ Find $($a$)$ the spring constant, $($b$)$ the mass of the block and $($c$)$ the frequency of oscillation.
