An express train passes through a station. It enters with an initial velocity of 21.2 m/s and decelerates at a rate of 0.160 m/s as it goes through. The station is 220 m long. (a) How long (in s) is the nose of the train in the station? S (b) How fast (in m/s) is it going when the nose leaves the station? m/s (c) If the train is 130 m long, when (in s) does the end of the train leave the station? S (d) What is the velocity (in m/s) of the end of the train as it leaves? (Enter the magnitude.) m/s An express train passes through a station.
