A gun fires a bullet of mass `50 g` with a velociy of `30 m//s`. Due to this, the gun is pushed back with a velocity of `1 m//s`, then the mass of the gun is :

A

15 kg

B

30 kg

C

1.5 kg

D

20 kg

Text Solution

Verified by Experts

The correct Answer is:
C

`m_(G)= (m_(B) v_(B))/(v_(G)) (50 xx 10^(-3) xx 30)/(1) = 1.5kg`
