Question

A gun of mass 4 kg fires a bullet of 10g with a speed of 100m/s in
the forward direction. Find
(i) The total initial momentum
(ii) Recoil velocity of gun.
(iii) Why is the recoil velocity of gun much less than the velocity of
bullet ?

Answer 1

Answer:

initial momentum

p=mv

p=4×100

p=400 kg/ms
