Physics - Kinematics Question with Solution | TestHub

Acceleration of a particle moving in $x-y$ plane varies with time $t$ as $\vec{a}=\left(t^2+3t^2\right)$, here $a$ is in $m/s^2$ and $t$ in $\sec$. At time $t=0$ particle is at rest at origin. Mass of the particle is 1 kg . Find the velocity (in $\mathrm{m}/\mathrm{s}$ ) of the particle at $\mathrm{t}=2$ seconds. Round of the answer to Nearest Integer.
