## Homework Statement

a train travels between stations one and two (station one is marked by "A", and station two is marked by "D". There are also the other points "B" and "C") the engineer of the train is instructed to start from rest at station 1 and accelerate uniformly between points A and B, then coast with a uniform velocity between points B and C, and finally accelerate uniformly between points C and D until the train stops at station 2. The distances AB, BC, and CD are all equal, and it takes 5 minutes to travel between the two stations. Assume that the uniform accelerations have the same magnitude, even when they are in opposite directions.

a.) How much of this 5 minute period does the train spend traveling between points A and B?

b.)How much of this 5 minute period does the train spend traveling between points B and C?

c.) How much of this 5 minute period does the train spend traveling between points C and D?

## Homework Equations

I have no idea which kinematic equations could be useful

## The Attempt at a Solution

so I tried to make a list of "givens"

AB {Vi= 0 m/s}

BC {a=0 m/s^2}

CD {Vf= 0 m/s}

total time: 5 minutes

AB=BC=CD

Acceleration for AB= Acceleration for CD
