A $5\mathrm{.}5-kg$ block attached to a spring executes simple harmonic motion on a frictionless horizontal surface. At time $t=0s,$ the block has a displacement of $-0\mathrm{.}70$ m $,$ a velocity of $-0\mathrm{.}80\frac{m}{s},$ and an acceleration of $+2\mathrm{.}0\frac{m}{s^2}.$ The amplitude of the motion is closest to:

A$)1\mathrm{.}2$ m

B$)1\mathrm{.}4$ m

C$)0\mathrm{.}84$ m

D$)2\mathrm{.}0$ m

E$)1\mathrm{.}1$ m
