Horizontal SpeedHorizontal Speed

A rescue airplane drops a relief package while it is moving with a constant horizontal speed. Assuming that air resistance is negligible, where will the package land relative to the plane? Explain.

Beneath the plane (position B) because the horizontal component of the velocity will not change.
