Man on a Flatbed: Inertia Prediction

[littlesohi]

Homework Statement

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 length 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
