Question

A bullet of mass 20g is filed horizontally
with a velocity of 150m/s from a pistol of mass 2 kg. what is the
recoil velocity of the pistol?​

Answer 1

Answer:

1.5 m/s

Explanation:

According to law of conservation of linear momentum

m1 × v1 = m2 × v2

mass of pistol = 2 kg

mass of bullet = 0.02 kg

velocity of pistol = 150 m/ s

let recoil velocity of the pistol be v1

2 × v1 = 0.02 × 150

2× v1 = 3

v1 = 3/2

v1 = 1.5

Ans 1.5 m/ s
