1. ## physics - subway train

Again with the maximum acceleration .. im not understanding how to get maximum values!

(a) If the maximum acceleration that is tolerable for passengers in a subway train is 1.64 m/s2 and subway stations are located 806 m apart, what is the maximum speed a subway train can attain between stations? (b) What is the travel time between stations? (c) If a subway train stops for 23.0 s at each station, what is the maximum average speed of the train, from one start-up to the next?
