- Superman is applying a 17,000 N horizontal force to try and stop a speeding locomotive. This train has a mass of {9004} kg, it is on level, horizontal track, and gravity in Metropolis is 10 N/kg. The train is originally travelling at 25 m/s, and the brakes have failed. (Friction force is zero). Draw a Force Body Diagram of the train, labelling and calculating all forces. What is the acceleration of the train? How many seconds does it take for Superman to stop the train? How far does the train travel in that time?5:03Don't Use Chat GPTSEE MORE QUESTIONS
