Let's just jump into it...

At the instant the light turns green, a car accelerates from rest at a rate of 1.8m/s^2. A truck gets to the intersection by the time the light changes [and therefore doesn't have to stop]. The truck is traveling at a constant velocity of 8.5m/s.

What will be the displacement of the car [assuming the intersection is 0] when it passes the truck, and at what time will this occur?

----------------

I've been trying to solve it by using a displacement-time graph, but obviously the car will have a curved graph, and I can't figure out the equation of it's line. Any tips on how to go about this, as well as tips to solve the question would be great.

Thanks!
