A light-rail train going from one station to the next on a straight section of track accelerates from rest at 1.4 { m/s^2} for 15 { s}. It then proceeds at constant speed for 1100 { m} before slowing down at 2.2 { m/s^2} until it stops at the station.

What is the distance between the stations?

How much time does it take the train to go between the stations?

2. Relevant equations

(v_{x})_{f}= (v_{x})_{i}+ a_{x}[tex]\Delta[/tex]t

x_{f}= x_{i}+ (v_{x})_{i}[tex]\Deltat[/tex] + 1/2a_{x}([tex]\Deltat[/tex])^{2}

(v_{x})_{f}^{2}= (v_{x})_{i}^{2}+2a_{x}[tex]\Deltax[/tex]

3. The attempt at a solution

I already know the answer but I cant figure outhowto get to the right answer....

d= 1400m

t=77s
