A mass $(m=1\mathrm{.}33kg)$ is connected to a spring of spring constant $k=60\mathrm{.}26\frac{N}{m}$ and set into simple harmonic motion along the $x-$axis about the point $x=0m.$ At time

$t=0s,$ the mass is located at vec$(r)(0)=-0\mathrm{.}212$mhat$(i)$ and traveling with velocity vec$(v)(0)=-1\mathrm{.}205\frac{m}{s}$hat$(i).$

What is the velocity of the mass at time $t=0\mathrm{.}753s?$

$\frac{m}{s}$hat$(i)$
