Two bodies of masses `10 kg and 2 kg` are moving with velocities `(2 hati - 7 hatj + 3hat k) and (-10 hati + 35 hatj - 3hatk) m//s` respectively. Calculate the velocity of their centre of mass.

Explanation

To find the velocity of the center of mass of the two bodies, we can use the formula for the velocity of the center of mass (V_COM) given by:

\[ V_{COM} = \frac{m_1 \cdot v_1 + m_2 \cdot v_2}{m_1 + m_2} \]

Where:
- \( m_1 \) and \( m_2 \) are the masses of the two bodies.
