Given; m1 = 5g; m2 = 2g;
\(\overrightarrow{v_{1}}=(\hat{i}+\hat{j}-\hat{k})\) cm/s and \(\overrightarrow{v_{2}}=(3 \hat{i}-2 \hat{j}+\hat{k})\); \(\vec{v}_{\mathrm{cm}}\) =?
The velocity of center of mass,
\(\vec{v}_{\mathrm{cm}}=\frac{1}{M}\left(m_{1} \overrightarrow{v_{1}}+m_{2} \overrightarrow{v_{2}}\right)\)
