Question

A gun of mass 40 kg has a bullet of mass 40 kg in it. after firing the bullet comes out from the barried of the gun with a velocity of 100m/second. what will the recoling velocity of gun ??​

Answer 1

Answer:

-100

Explanation:

40×100+40V = 4000+40V

4000+40V=0 (linear momentum is zero)

40V=-4000

V=-4000/40

V=-100
