A bullet of mass 10 g is fired with a velocity of 400 m/s from a gun of mass 4 kg. What is the recoil velocity of the gun?

Here no external force is acted (neglect air resistant) hence momentum of system(gun+bullet) is conserved 
initial momentum = finial momentum
let the recoil velocity of gun = v
0.01*0 + 4*0 = 0.01*400 + 4*v
v = -1m/s
hence gun recoil with velocity 1m/s ☺️

Given: -

▶M1 = 4kg (mass of gun)

▶M2= 10g =0.010kg (mass of bullet)

▶V1=? ( velocity of gun)

▶V2=400m/s (velocity of bullet)

▶M1 × V1=M2 × V2

▶4 × V1=0.010 × 400

▶V1=4/4

▶V1=1m/s

Recoil velocity of the gun =1m /s
