A bowling ball of mass m and radius r has a coefficient ofstatic friction µ when in contact with an oiled wood surface. Modelthe ball as a solid uniform sphere. The surface is inclined at anangle θ with respect to the horizontal. What is the maximum angleof inclination of the surface such that the ball rolls withoutslipping? How does the angle change if the ball is now a hollowshell with all its mass concentrated at the rim? Explain
