An express train passes during a station which is 210 m long. It enters with an initial velocity of 20.5 m/s and decelerates at a rate of 0.14 m/s   2 as it goes through.

1. How long, in seconds, is the front of the train in the station?

2. How fast is it going when the nose leaves the station in m/s?

3. What is the velocity of the end of the train as it leaves in m/s?

4. If the train is 122 m long, how long, in seconds, after the front of the train enters the station does the end of the train leave the station?
