1. The problem statement, all variables and given/known data http://imageshack.us/photo/my-images/96/caracarbgraph2.png/[PLAIN] [b]2. Relevant equations[/b] This image is 2 cars, and Car 1 is starting at a higher velocity rate than Car 2, which is constant @ t = 0. Now then, the car is ahead and then decreases speed over time, I am trying to figure out when car 2 well eventually catch up to car 1. [b]3. The attempt at a solution[/b] I am not sure if there is any equation to this, but it looks like they go the same speed at 5 seconds, the slope of car 1 is 6 m/s^2 (70 m/s - 10 m/s = 60 m/s/10s = 6m/s^2) However I'm not even sure if that actually helps.. since car 2 has a slope of 0.
