Question

A 5kg gun fires a bullet of 15g at a velocity of 1000m/s to the right,what is the velocity of recoil of the gun correct answer

Answer 1

Answer:

3 m/s

Explanation:

We know that momentum is conserved according to law of conservation of momentum

Hence

Momentum of gun (recoil)=Momentum of bullet

5kg*recoil velocity=15kg/1000*1000m/s

Recoil velocity is 3m/s

Answer 2

Answer:3m/s

Explanation:

We know that momentum is conserved according to law of conservation of momentum

Hence

Momentum of gun (recoil)=Momentum of bullet

5kg*recoil velocity=15kg/1000*1000m/s

Recoil velocity is 3m/s
