A 73.3-kg linebacker ("X") is running at 6.71 m/s directly toward the sideline of a football field. He tackles a 91.7-kg running back ("O") moving at 8.61 m/s straight toward the goal line, perpendicular to the original direction of the linebacker. As a result of the collision both players momentarily leave the ground and go out-of-bounds at an angle φ relative to the sideline, as shown in the diagrams below. What is the common speed of the players, immediately after...
