Question

Two bodies having masses $m_{1}$ and $m_{2}$ and velocities ${\overrightarrow{u}}_{1}$ and ${\overrightarrow{u}}_{2}$ collide and form a composite system of $m_{1}{\overrightarrow{v}}_{1} + m_{2}{\overrightarrow{v}}_{2} = 0(m_{1} 
eq m_{2})$. The velocity of the composite system is

(a) Since net momentum of the composite system is zero, hence resultant velocity of the composite system should also be zero.
