Atrain is traveling down a straight track at 20. m/s when the engineer applies the brakes, resulting in an acceleration of -1.0 m/s2 as long as the train is in motion. how far does the train move during a 40. s time interval starting at the instant the brakes are applied? [double-check that your answer makes logicalsense.
