"A Metra train is at rest at the train station. You are running with a constant speed of 4.0 m/s. When you are 75.0 m from the back end of the train, the train begins accelerating away from you at 0.12m/s^2. Can you catch the train? If so, when? If not, how close do you get?"
I have figured out that you do not catch the train. However, I am having trouble figuring out how close you get.
