Step 1
Which of the following is the reason why the car slides off the track?
Answer
The car slides off the track at point P due to insufficient frictional force. While centripetal force is necessary to keep the car moving in a circular path, if the frictional force between the tires and the track is not large enough to provide the required centripetal force, the car will lose its grip and slide off. Therefore, the correct answer is D: The frictional force is not large enough.
