## Homework Statement

A red car is sitting at a stop light at rest. When the light turns green two things happen simultaneously; (1) the red car accelerates to a speed of 34.3 m/s in 8.92 seconds and then maintains that 34.3 m/s speed and (2) a blue car passes by the red car at a constant speed of 21.5 m/s.

Red Car: Vo=0 Vf=34.3 m/s a=3.84 (34.3/8.92)

Blue Car: Vo=21.5 m/s Vf=21.5 m/s

How much time (in seconds) will have elapsed from when the light turned green until the two cars are side-by-side?

## Homework Equations

distance = 1/2(Vo + Vf)t

distance = Vot + 1/2at^2

## The Attempt at a Solution

I thought I would make them equal to each other, 1/2(Vo +Vf)t=Vot +1/2at^2 And find out what t equals to find out the time however It has yet to work after many attempts. Vo Any help is appreciated.
