SUMMARY
The physics problem involves a collision between a running back with a mass of 80 kg moving at a speed of 8 m/s and a defensive tackle with a mass of 120 kg. To achieve a final speed of zero after the collision, the tackle must be moving at a speed of 5.3 m/s in the opposite direction. This conclusion is derived from the conservation of linear momentum, where the total momentum before the collision equals the total momentum after the collision.
