A train with two hundred cars takes miles to stop? - Answers

Yes, it can. Train braking systems are not that powerful and a large train can take over a mile to come to a stop.Consider the physics. The kinetic energy of a train is given by: KE = 1/2 m v2The work to stop a train is F d, where F is the stopping force provided by the brakes and d is distance.So F d = 1/2 m v2. This tells you that if you double the speed of the train, you increase the stopping distance by 4 fold! If you double the mass of the train (the number of cars) you double the stopping distance.The web site below gives some figures on train braking distance.http://homepage.ntlworld.com/wilf.james/trains.htm
