Homework Help: Two cars with constant acceleration meeting

  1. Sep 22, 2015 #1
    1. The problem statement, all variables and given/known data
    Two cars travel towards one another on a 21.0m road, the car traveling to the left has an acceleration a_L=2.4m/s^2 the other car an a_R=1.8m/s^2. What is the distance traveled by the left car up to the meeting point?

    2. Relevant equations
    Left Car Right Car
    ------->1.8m/s^2 2.4m/s^2<-------

    3. The attempt at a solution
    So the left car should have traveled 9 meters and the right 12m, but it's not right and I don't see why.

    Looks like you've calculated the distance for the car moving right rather than the car moving left.
