A 84.1 kg linebacker (X) is running at 7.55 m/s directly towardthe sideline of a football field. He tackles a 86.5 kg running back(O) moving at 9.05 m/s straight toward the goal line, perpendicularto the original direction of the linebacker. As a result of thecollision, both players momentarily leave the ground and goout‑of‑bounds at an angle 𝜙 relative to the sideline, as shown inthe diagrams.
1) What is the common speed 𝑣f of the players immediately aftertheir impact?
2) What is the angle 𝜙 of their motion relative to thesideline?
