Abstract: The general Zeno paradox refers to a bird flying back and forth between two face-to-face moving carts. The bird is finally located at the position where the two carts meet, and this final position is independent of where the bird initially is. Hence, it is concluded that for its reversed course, i.e. the bird starts moving in its final position while the two carts go in a back-to-back way, the bird would not necessarily return back to its initial position at the end. In this work, we analyzed this paradox related process by building physical models based on the motion laws, and solved this problem.

Key words: Zeno paradox, acceleration, uniform motion, impact process
