Two MMA fighters start to throw a spinning back fist. This maneuver involves spinning about blindly in a circle with arms outstretched until you make contact with your opponent. The fighters are spinning with the same angular velocity and their fists make contact with the others face at the exact same time. Why did the fighter with the longer arms "own" the other $($hot him harder$)$ in the end? What is an associated kinematic equation that supports your answer.
