## Homework Statement

Two cars are at rest, facing each other, and 300 metres apart.

If car 1 accelerates at 6.00m/s^2 up to a maximum speed of 30.0m/s and car 2 accelerates at 5.00m/s^2 up to a maximum speed of 35.0m/s, how long does it take the cars to meet?

## Homework Equations

vf= vi + at

d= (vf + vi/2) * t

## The Attempt at a Solution

Car 1

t = 5.00s

Car 2

t = 7.00s

After 5.0s Car 1 has traveled 75m

After 7.0s Car 2 has traveled 123m

That's as far as I got...i can't seem to figure out how long it takes for the two cars to meet..help please? I don't know if the numbers i have already are correct or not?

Thanks.
