1. A linebacker of mass 95kg is closing in on a running back of mass 85kg. After they collide, they are momentarily stuck together and both are moving at a speed of 4.5 m/s in the initial direction of the inebacker. If the running back was moving at 2.5 m/s towards the linebacker before contact, how fast was the linebacker moving just before the collision?
