A particle moving along the $x$ -axis has its velocity described by the function $v_{x}=2 t^{2} \mathrm{m} / \mathrm{s},$ where $t$ is in $\mathrm{s}$. Its initial position is $x_{0}=1 \mathrm{m}$ at $t_{0}=0 \mathrm{s} .$ At $t=1 \mathrm{s}$ what are the particle's (a) position, (b) velocity, and (c) acceleration?
