An MSU linebacker of mass 112.0 kg sacks a UM quarterback of mass 84.0 kg. Just after they collide, they are momentarily stuck together, and both are moving at a speed of 2.50 m/s. If the quarterback was at rest just before he was sacked, how fast was the linebacker moving just before the collision? (in m/s)
