## Homework Statement

A vehicle Accelerates from rest (a) and travels a certain distance s1 It then deccelerates (a) at a constant rate and travels a second distance s2 until it stops. If s2/s1 = K then what is the accleration (a) of the vehicle.

## Homework Equations

v=u+at

s=ut+1/2at^2

s=vt-1/2at^2

v^2=u^2 + 2as

s=(u+v)t/2

## The Attempt at a Solution

I used v^2=u^2 + 2as to describe the two parts of the journey but I ended up at a completely incorrect answer.
