Question

A small marble is placed in the bottom of a large bowl. If the marble is given a small push it will oscillate back and forth about the bottom of the bowl, moving along a small arc with radius 0.50 m. Assuming the marble rolls without slipping what is the period of this oscillation? Hints: use the moment of inertia for a solid sphere and the small angle approximation q = sin(q ) – this is true if the angle is small and measured in radians.
