A 90.0 kg fullback attempts to score a touchdown by diving over the goal line. When he is at the goal line and moving horizontally at 7.50 m/s, he is met in midair by an opposing 111 kg linebacker, who is initially moving at 4.00 m/s in the opposite direction. The two meet in a head-on collision at the goal line. Does the fullback cross the goal line? Find the total linear momentum of the two players.
