Question

5g Bullet shooted from gun which is 250g then Bullet moves with the speed of 200 metres per second what is speed of gun​

Answer 1

Answer:

apply conservation of momentum

initial momentum = final momentum

0={(5/1000)×200}+{(250/1000)×v}

v=-4 m/s

Answer 2

Answer:

momentum of bullet = momentum of gun

0.005x200= 0.25x speed

400 m/s.
