Answer: the answer is 0.016 m/s
Explanation:
See the attachement for explaination....
Last point : -The direction of gun is opposite to the direction of shell...
Mark me as brainliest answer....
Answer:
Hlo mate here's your answer Hope it helps....
Mass of gun M = 100kg
mass of shell m = 0.020kg
Velocity of shell v = 80m/s
Recoil velocity of Gun V=?
initial velocities of both gun and shell will be zero
so, the initial momentum of the system will be zero.
According to the law of conservation of momentum,
Initial momentum = Final momentum
so,
0=mv-MV
∴v=mv/M
=
=0.016 m/s
∴recoil velocity of Gun=0.016m/s
