Problem 2 – variation of problem 10.76: A thin- walled, hollow spherical shell of mass m and radius r starts from rest and rolls without slipping down the track shown in the figure. Points A and B are on a circular part of the track having radius R. The diameter of the shell is very small compared to ho and R, and the work done by rolling friction is negligible.
a) What is the minimum height ho, for which this shell will make a complete loop-the- loop on the circular part of the track?
b) How hard does the track push on the shell
at point B, which is at the same level as the center of the
circle?
c) Suppose that the track had no friction and the shell was released from the same height ho you found in part a. Would it make a complete loop-the-loop? How do you know?
d) In part c, how hard does the track push on the shell at point A, the top of the circle? How hard did it push on the shell in part a?

1. (20 points) A hollow sphere of radius r and mass m starts from rest and rolls down the mountainside and then up the opposite side, as shown in Figure 1. The initial height is Ho. The rough part prevents slipping while the smooth part has no friction. The horizontal surface is smooth. How high, in terms of Ho will the sphere roll up the other side? Rough Smooth
