Two bodies of 6 kg and 4 kg masses have their velocity $5 \hat i+ 2 \hat j +10 \hat k$ and $10 \hat i - 2 \hat j -8 \hat k$ respectively. Then the velocity of their center of mass is
\[\begin {array} {1 1} (a)\;5 \hat i+ 2 \hat j-8 \hat k & \quad (b)\;7 \hat i+ 2 \hat j-8 \hat k \\ (c)\;7 \hat i - 2 \hat j + 8 \hat k & \quad (d)\;5 \hat i - 2 \hat j +8 \hat k \end {array}\]

Two particles of equal mass have velocities $\overrightarrow {v_1}=4 \hat i$ and $\overrightarrow{v_2} =4 \hat j ms^{-1}$. First particle has an acceleration $\overrightarrow{a_1}=(5 \hat i+5 \hat j)ms^{-2}$ while the accleration of the other particle is zero. The center of mass of the two particles moves in a path of :
