Please help!! - using your knowledge of velocity, kinetic energy and trajectory explain how a handgun round becomes less effective than a rifle bullet over long distances.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
