(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

(a) If the maximum acceleration that is tolerable for passengers in a subway train is 1.54 m/s2 and subway stations are located 816 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 20.0 s at each station, what is the maximum average speed of the train, from one start-up to the next?

2. Relevant equations

velocity & time:

v = v_0 + a t

displacement & time:

x = x_0 + v_0 t + (1/2) a t^2

velocity & displacement:

v^2 = v_0^2 + 2 a \\Delta x

3. The attempt at a solution

I tried the displacement and time equation for part A and it didn't work. I had no idea how to do the other two parts.

How do you start this problem?
