Two students are running down the hallway towards each other. Student 1 has a mass of 107kg and is running to the right at 4.1m/s. Student 2 has a mass of 97kg and is running to the left at 7.1m/s. If they strike in an elastic collision, what is the velocity of student 2 if student 1 moves at 6.55m/s to the left after the collision?
