A train is traveling south at 65.8 m/s when the brakes are applied. It slows down with constant acceleration to a speed of 6.00 m/s in a time of 9.00 s. a.)What is the acceleration of the train during the 9.00-s interval? If the acceleration is toward north, enter a positive value. If the acceleration is toward south, enter a negative value. b.)How far does the train travel during the 9.00 s? If the displacement is toward north, enter a positive value. If the displacement is toward south, enter a negative value.
