An iceboat is traveling in a circle on the ice. Halfway around the circle, the sail and the steering mechanism fall off the boat. Which will most likely occur as a result?
A. The boat will continue traveling in a circle, because there is no friction.
B. The boat will continue to travel in a circle, because its velocity exerts a force on it.
C. The boat will move off on a line tangent to the circle, because there is no net force on it.
D. The boat will move off tangent to the circle because there is a force on it perpendicular to the boat, and directed to the outside of the circle.
E. The boat will move off to the outside, perpendicular to the tangent line, because a force directed to the outside of the circle always acts on the boat.
