A train leaves a station from rest and travels with uniform acceleration. It attains a maximum speed

Question

A train leaves a station from rest and travels with uniform acceleration. It attains a maximum speed of $20$ ms$^{-1}$ after $4.8$ km. After which it slows down with a uniform acceleration of $-0.25$ ms$^{-2}$ to stop at the next station. Find the distance between the stations and the total time of the journey.

Take the direction towards the next station as positive.

Accepted Answer

Distance $=5.6\text{ km}$; total time $=560\text{ s}$
