Draw a motion diagram and a free-body diagram for a roller coaster car at the top of a "loop-de-loop" (i.e., when the car is upside down). Do not ignore air resistance, and assume that the car is moving rapidly enough to remain in firm contact with the rails. In particular, explain why there is no outward force on the car.
