hey mate ur ans
The source of the kinetic energy is chemistry. It comes from the chemical energy of the white gun powder that converts it into kinetic energy in the form of a velocity mass vector. There's “gunpowder” in the shell casing. When that burns, it makes hot gas that pushes the bullet out the front of the gun at high speed.
