Answer:
0
Explanation:
Since momentum is given by:
[tex]\vec{p}=m.\vec{v}[/tex]
Therefore momentum is a vector quantity in the direction of velocity.
This case can be described mathematically as:
[tex]m_1.\vec{v_1}=m_2.\vec{v_2}[/tex]
since the mass and velocity are equal:
[tex]m.\vec{v}=m.\vec{v}[/tex]
net momentum:
[tex]p_{net}=0[/tex]
