    1. The problem statement, all variables and given/known data


    2. Relevant equations


    3. The attempt at a solution

    Look, the question is there is a runway that is 300 meters long. how many meters per second per second must the plane accelerate if it must have a velocity of 120 KM per hour. I already know the awnser, i just need to know how to do it.

    Well, what does Xf stand for? How about V0?
