Conservation of momentum means the gun's backward kick equals the bullet's forward momentum. If a 0.02 kg bullet fires at 300 m/s, the 2 kg gun recoils at 3 m/s—because (0.02)(300) = (2)(3). My kid used my paint jars for his model, and now my art supplies are a physics crime scene. The only thing conserved here is my regret for helping.
