Question

bullet of mass 20g is fired with a velocity 150m/s from a gun of mass 5kg ,. What is the recoil velocity of the gun ? *

1 point

0.6m/s

- 0.6m/s

6m/s

- 6 m/s

​

Answer 1

Answer:

0.6 is the correct ans.

Coz:---- Initial momentum of the system is 0 as it is at rest.

Initial momentum of the system is 0 as it is at rest.After firing-----MV=mv

⟹V= MV=mv

0.02×150

5

⟹V=0.6m/s

Hope this is helpful.....
