In the design of a rapid transit system, it is necessary to balance the average speed of a train against the distance between stops. The more stops there are, the slower the train's average speed. To get an idea of this problem, calculate the time it takes a train to make a 6.0 trip in two situations. (Assume that at each station the train accelerates at a rate of 1.1 until it reaches 95 , then stays at this speed until its brakes are applied for arrival at the next station, at which time it decelerates at -2.0 . Assume it stops at each intermediate station for 23.0 .) a.Calculate the time it takes a train to make a 6.0 trip if the stations at which the trains must stop are 1.2 apart (a total of 6 stations, including those at the ends). b.Calculate the time it takes a train to make a 6.0 trip if the stations are 3.0 apart (3 stations total). Please help me to get started on this problem. What kind of equation I should us? Thank you.
