Question

a bullet of mass 20 g is fired from a gun of 5 kg with a velocity of 300m/s recoil velocity is?​

Answer 1

Answer:

Initial momentum of the system P

i

=0

Given: M

bullet

=0.02 kg V

bullet

=100 m/s M

gun

=8 kg

Let the recoil velocity of gun be V.

Applying the conservation of linear momentum : P

f

=P

i

Or M

gun

V+M

bullet

V

bullet

=0

Or 8V+0.02×100=0

⟹ V=−0.25 m/s
