Need help w/ Acceleration of a Freight Train problem

  1. Feb 5, 2007 #1
    Question: A freight train has a speed of 29.8 m/s at a given instant and 9.2 seconds later its speed is 26.2 m/s.
    train's acceleration is -3.91×10-1 m/s^2

    What additional time would be necessary to bring the train to a complete stop, if it continues to slow at the rate given?

    What total distance is travelled in stopping during the entire slowing phase?
