    Finding speed and distance of a train

    1. Homework Statement A train has a mass of 5.77E+6 kg and is moving at 99.4 km/hr. The engineer applies the brakes, which results in a net backward force of 1.11E+6 N on the train. The brakes are held on for 26.9 s. What is the new speed of the train? How far does it travel during...
