Homework Equations
The Attempt at a Solution
At first I thought this was Newton First law. Reason is because the guy the person is at rest but when the train starts moving east, the person is jerked backward and therefore he moved west. However the question doesn't say the train was suddenly acceleration forward so i don't believe this is the right answer.
I then thought about how this can also be seen as relative motion: the person is already moving west. The person must also be walking at a speed greater than the speed of the train to make it look like the person is moving west. Then when the train starts to accelerate and once the trains speed is greater that the person's, the person will no longer be seen moving west
I am torn on which answer it is
