A 1500 kg car traveling at 80 km/h requires about 38 meters to stop if you apply the brakes. A 2.0 x105 kg train, traveling at 40 km/h may require as much as 1 km of track to safely stop once the brakes are applied. Using the concepts of momentum and Newton's Laws, discuss why it is possible to bring the car to a stop quite easily, but the train requires several kilometers of track to slow down and stop. In your response address: 0 The relative mass of the objects 0 The reason initial velocity alone cannot explain the difference in stopping distance. 0 The role of the tracks/road in stopping the vehicle
