train is traveling south at constant speed 12.0 m/s. Then the brakes are applied & it slows down with a constant acceleration to a speed of 3.00 m/s in a time of 9.00 s. (a) Draw a graph of speed versus time for a 12-s interval (starting 2 s before the brakes are applied and ending 1 s after the brakes are released). (b) What is the acceleration of the train during the 9.00-s interval? (c) How far does the train travel during the 9.00 s?
