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

Two train cars are on a straight, horizontal track. One car starts at rest and is put in motion with a constant acceleration of 2.4 m/s2. This car moves toward a second car that is 29 m away and moving at a constant speed of 4.0 m/s.

a.) where will they collide

b.) how long will it take to collide

2. Relevant equations

3. The attempt at a solution

My original plan to solve this problem was to set up two seperate Kinematics equaitons .

I also put a negative sign infront of - 4.0m/s. My answer came out like 8.743 s .

ANY HELP OR ANY ADVICE WOULD BE GREAT
