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 statement is correct?
a. The boat will continue traveling in the circle because there is no friction.
b. The boat will continue to travel in the 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 force on it.
d. The boat will move off tangent to the circle because there is a force on it perpendicular to the boat directed to the outside of the circle.
e. The boat will move off to the outside perpendicular to the tangent line since a force directed to the outside of the circle always acts on the boat.
