Solve Kinematics Problem: Car Overtaking Truck

[fxsnowy]

I need help with this problem. Any help is greatly appreciated.

Homework Statement

At the instant the traffic light turns green, a car that has been waiting at an intersection starts ahead with a constant acceleration of 3.40m/s^2 . At the same instant a truck, traveling with a constant speed of 17.5m/s , overtakes and passes the car.

Homework Equations

How far beyond its starting point does the car overtake the truck?

How fast is the car traveling when it overtakes the truck?

There is no specific time given, so i tried to use the formula v^2f = v^2i + 2a(xf-xi).
But for the car, I can't solve for the final velocity since I don't have the final position x so I don't know how to go about solving this.

May I ask if you have the answer to question 1? I have an answer but I want to ensure it's correct.

Also ask yourself, at the instant the car overtakes the truck, what is common between the two so I can equate something?
