What the work energy theorem of a rifle with a longer barrel that fire bullets with a larger velocity than a rifle with a shorter barrel?

The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. In the case of rifles, the longer barrel allows for a longer acceleration distance for the bullet, resulting in a higher muzzle velocity. This means that the rifle with the longer barrel does more work on the bullet, giving it more kinetic energy and a higher velocity compared to the rifle with the shorter barrel.
