Question

A train connection linking Munich airport and Munich city center needs to be optimized. The ride with 11 stops in between takes 41 minutes. Assume that all stops are equally spaced. The train is parking 1 minute at each station. It is driving at a maximum speed of 130 km/h and the maximum acceleration (and deceleration) is determined by the kinetic friction coefficient, which is 0.1 (steel wheels on the tracks). Calculate the distance the train is travelling! Calculate the time the ride would take is there were no stops in between

Follow-up Question

You did not take the value of the kinetic friction coefficient into the calculation at all. Arso, how do you know that the time total time equal time for accelelation + time for decelelation? It is also possible that it has a time that the velocity is constant at 130km/h. Also, how can you assume that the acceleration equal to the deceleration?
