(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement

At the instant when the traffic light turns green, a car starts with a constant acceleration of 1.8 m/s^2 [forward]. At the same instant a truck traveling with a constant velocity of 8.5 m/s [forward] overtakes and passes the car. How far from the starting point will the car catch up to the truck?

2. The attempt at a solution

Car:

d = V1*t + 1/2*a*t^2

d= 0 + 1/2(1.8)(t)^2

d= 0.9t^2

Truck:

d = V * t

d = 25t

Put it all together

0.9t^2 = 25t

0.9t^2 - 25t = 0

Now what?
