mass of block with bullet = 0.5 + 0.050 = .55 kg 
momentum of block with bullet = 0.55 x 4 
= 2.2 kg m/s 
then 
0.050 V(bullet) = 2.2 

V(bullet) = 44 m/s 

The momentum was zero before shoting
so, 
0 = mass pistol x 0 + mass bullet x 0 
=0

0 = 2 V(gun) + momentum of bullet 
= = 2 V(gun) + 2.2 
Vgun = - 1.1 m/s
