Textbook Question
Chapter 9, Problem 12CQ
A uniform marble rolls down a symmetric bowl, starting from rest at the top of the left side. The top of each side is a distance h above the bottom of the bowl. The left half of the bowl is rough enough to cause the marble to roll without slipping, but the right half has no friction because it is coated with oil. Would the height the marble reaches on the right side of the bowl be less than h, equal to h, or greater than h (meaning that the marble would fly out of the bowl)? Explain your answer.
