Question

A bullet of mass 0.02kg is horizontally fired with a velocity of 200 m/s from a
pistol of mass 4 kg. Calculate the recoil velocity of the pistol.​

Answer 1

Answer:

initial momentum of the system is 0 as it is at rest

After firing -

MV= mv

V=mv/M = 0.02×150

2

V= 1.5m/s

Answer 2

Answer:

V=1.5m/s...........
