Two cars are on a straight, horizontal track. One car starts at rest and is put in motion with a constant acceleration of 2 m/s². This car moves toward a second car that is 40 m away. The second car is moving away from the first car and is traveling at a constant speed of 5 m/s. How long will it take for the cars to collide?
