Velocity of the gun=1m/s^2
As,pressure of gun=pressure of bullet.

mass of bullet=m=10g=0.01kg
mass of gun=g=2kg
m*u + g*u= m*v + g*v
as gun and bullet are in rest so u=0
0 + 0=0.01*100 + 2*v
0=1+2*v
-1=2*v
so recoil velovity of gun= -0.5m/s
mass of gun=g=2kg
m*u + g*u= m*v + g*v
as gun and bullet are in rest so u=0
0 + 0=0.01*100 + 2*v
0=1+2*v
-1=2*v
so recoil velovity of gun= -0.5m/s
