A spring$-$mass system is undergoing simple harmonic motion of amplitude $2\mathrm{.}2$ cm and angular frequency $10\mathrm{.}3$ s$1.$ The magnitude of the maximum acceleration of the mass as it oscillates back and forth is

$0\mathrm{.}00$ m$/$s$2\mathrm{.}0\mathrm{.}21$ m$/$s$2\mathrm{.}2\mathrm{.}33$m$/$s$2\mathrm{.}14\mathrm{.}7$ m$/$s$2.$
