Question
An express train passes through a station. It enters with an initial velocity of 22.0 m/s and decelerates at a rate of $0.150 \textrm{ m/s}^2$ as it goes through. The station is 210 m long. (a) How long is the nose of the train in the station? (b) How fast is it going when the nose leaves the station? (c) If the train is 130 m long, when does the end of the train leave the station? (d) What is the velocity of the end of the train as it leaves?
1. $9.88 \textrm{ s}$
2. $20.5 \textrm{ m/s}$
3. $16.4\textrm{ s}$
4. $19.5 \textrm{ m/s}$
