Two particles A and B of equal masses have velocities $\overrightarrow{v_A}=2 \hat{\imath}+\hat{\jmath}$ and $\overrightarrow{v_B}=-\hat{\imath}+2 \hat{\jmath}$. The particles move with accelerations $\overrightarrow{a_A}=-4 \hat{\imath}-\hat{\jmath}$ and $\overrightarrow{a_B}=-2 \hat{\imath}+3 \hat{\jmath}$ respectively. The centre of mass of the two particles moves along
