Question

A gun of mass 3kg fires a bullet of mass 30g . The bullet takes 0.003s to move through the barrel of the gun and acquires a velocity of100 m/s .calculate velocity o

Answer 1

Momentum of bullet=momentum of gun

Let the recoil velocity or acceleration of the gun be v

Mass of bullet×velocity=mass of gun× recoil velocity

0.03kg×100m/s =3kg×v

3=3v

V=1m/s(ans)

Answer 2
