Question

On October 7, 2017, MSU and UM played in Michigan Stadium in Ann Arbor. MSU prevailed 14-10. In the game, MSU defensive end Kenny Willekes sacked UM quarterback John O'Korn. Just after they collided, the two players were momentarily stuck together, and both moved at a speed of 2.50 m/s. Kenny Willekes's mass was 109.5 kg and John O'Korn's mass was 93.3 kg. If the quarterback was at rest just before he was sacked, how fast was the defensive end moving just before the collision?
