Question 13 (1 points) Consider a roller coaster with a single, circular loop of radius R. Assuming no friction and no external driving once the car reaches the top of the first hill, at what height must the car start in order to make it around the loop? Assume that the car wheels cannot grip the rails, so that if the normal force at the top drops to zero then the car will fall off the loop. Give your answer...
