A running back with a mass of 80-kg and a speed of 8 m/s colides with, and is held by, and 120-kg defensive tackle going in the opposite direction. How fast must the tackle be going before the collision for their speed afterward to be zero? NOTE: here you must set up a coordinate system. Choose the running back's direction to be positive and the defensive tackle's to be negative.
