Homework Help: Man on a flatbed

  1. Aug 24, 2011 #1
    1. The problem statement, all variables and given/known data

    A flatbed railcar is moving at a slow but constant velocity. A man stands in the railcar, facing sideways (perpendicular) to the motion of the railcar. The man holds a baseball at arm's lenght and drops it onto the railcar bed. Where does the principle of inertia predict that the ball will land?

    A. slightly behind the drop point
    B. directly below the drop point on the railcar
    C. Need to know the speed of the railcar
    D. slightly in front of the drop point on the railcar

    2. Relevant equations

    3. The attempt at a solution

    so, what do you think inertia is about?
    Do you think that the ball won't fall?
    tell us what you're thinking!
