## Homework Statement

A lamborghini's breaking speed is 6.7 times that of its acceleration. The total time taken to go from 0 to 100 and back to 0 is 13.7 seconds. What is the displacement of the car?

## Homework Equations

Unsure at the moment

## The Attempt at a Solution

So, you divide the treck into 2 parts: Acceleration and Breaking

Acceleration:

a= x

t= y

d= ?

Vo = 0

Vf = 100

Breaking:

a= -6.7x

t= 13.7 - y (y being the accelerating time)

Vo= 100

Vf = 0

d=?

Honestly I am unsure as to what to do :S, any help would be much appriciated.
