A) It will gradually slide down the bank.
B) It will continue to follow the curve as if there were no ice.
C) It will gradually slide up the bank.
D) It will quickly slide up the bank.

When a car moves at a speed higher than the one for which the curve is banked (in this case, faster than 15 m/s), and assuming there is no friction (as during an ice storm), the centripetal force required to keep the car moving in a circle increases. Since there's no friction to provide this extra force, the only way the car can maintain its circular path is by moving to a part of the bank where the component of its weight can provide the necessary centripetal force. This results in the car sliding up the bank.
