Find the position vector for a particle with acceleration, initial velocity, and initial position given below.

a(t)=2t,2sin(t),cos(6t)\displaystyle \vec{{a}}{\left({t}\right)}={\left\langle{2}{t},{2}{\sin{{\left({t}\right)}}},{\cos{{\left({6}{t}\right)}}}\right\rangle}

v(0)=4,5,0\displaystyle \vec{{v}}{\left({0}\right)}={\left\langle-{4},-{5},{0}\right\rangle}

r(0)=2,5,5\displaystyle \vec{{r}}{\left({0}\right)}={\left\langle-{2},{5},-{5}\right\rangle}

r(t)=\displaystyle \vec{{r}}{\left({t}\right)}=
