Question

A gun of 5 kg shot out a bullet of 5g at 100 m/s what is the recoil velocity of the gun?

Answer 1

yes

Answer 2

linear momentum =0.5

Answer 3

the recoil velocity of the gun is 0.04 m/s.

Answer 4

explanation
m1=5kg=5000g u1=0 v1=x m/s
m2=5g u2=100 m/s v2= 0

m1u1+m2u2=m1v1+m2v2
5000*0+5*100=5000*x+5*0
500=5000x
therefore, x=500/5000=0.04 m/s.
