Question

a bullet of mass 20 gram fired from a gun of mass 100 kg with a velocity 80 m/s.find recoil velocity of gun ​

Answer 1

Answer:

Mass of gun,M=100kg

Mass of bullet,m=20g = 0.02kg

Velocity of bullet =80m/s

Let recoil velocity of gun be v m/s.

Since Fnet(horizontal)=0

So, delta(P)=0

0.02×80=100v

v=1.6/100

v=0.016m/s
