Question

Gun of mass 1kg fires bullet of 1g with velocity 1m/s then recoil velocity of gun is??

Answer 1

hope it helps...... :)

Answer 2

Answer:

Explanation:

1) According, to the third law of motion by newton, every action has an equal and opposite reaction.

2)  so, if the bullet exerts a momentum when going forward, same amount of momentum will push the gun backward

3) Hence, the momentum of both would be equal

10 g *  v = 1000 g * 5 m/s

v = 500 m/s
