It recoils due to conservation of momentum of system.
Iniatial momentum of gun = Final momentum of gun
0 = m1v1 + m2v2
{tex}v_2 = -{m_1v_1 \over m_2}{/tex}
(-ve sign because velocity of gun is in opposite direction of bullet)
{tex}Recoil \ velocity = -v_2 = {m_1v_1 \over m_2}{/tex}
Where
m1 and m2 are masses of bullet and gun respectively
v1 and v2 are velocity of bullet and gun respectively
