Question

A gun having mass 50 kg fired A bullet of mass 10 g with a velocity of 15 M/S find recoiling velocity of gun​

Answer 1

Answer:

V= -0.003m/s

Explanation:

Given:

Mass of gun (M)= 50kg

Velocity of the gun (V)=?

Mass of bullet (m)= 10g or 10/1000kg=0.01kg

Velocity of bullet (v)= 15 m/s

According to the law of conservation of momentum

Momentum of bullet = Momentum of gun

⇒m×v = -M×V

⇒ 0.01×15 = -50×V

⇒0.15 = -50V

⇒ V = -0.15/50

⇒V = -0.003 m/s

Velocity is in minus because the gun is recoiling i.e. it is going in backward direction from its original position.
