Question

a gun of mass 2kg fired a bullet of 20 grms and the velocity after 5 sec of firing is 200m/s.recoil the velocity??

plz answer my question in detail and as fast as possible​

Answer 1

Answer:

2 m/ s

Explanation:

Mass of gun =2 kg

Mass of pistol =2 g=0.02kg

According to law of conservation of momentum MV= -MV

0.02×200= -2×V

V= -0.02×200÷2

V= -2 m/s
