Question

A
gun of mass 5kg
fires a bullet of mass
100 gm- with a velocity of
20m/s. Find the so velocity
of
of recoil
of the gm​

Answer 1

Explanation:

Let mass and velocity of ball be m1=0.05kg and velocity v1=200m/s.

Let mass of gun be m2=5kg and recoil velocity be v2

Use conservation of momentum.

m1v1=m2v2

(0.05)×(200)=(5)v2

V2=2m/s.
