(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A train is moving parallel and adjacent to a highway with a constant speed of 33 m/s. Initially a car is 32 m behind the train, traveling in the same direction as the train at 47 m/s and accelerating at 4 m/s^2.

What is the speed of the car just as it passes the train? Answer in units of m/s.

2. Relevant equations

So far, I have thought of using delta x= Vot+ 1/2at^2

I also think that I have to account for the displacement between the two trains, which is 14 m.

The thing that I don't understand is how to calculate something as it passes or catches up to another thing.

If there is any advice, thanks!
