A small ball rests at the bottom of a watch glass of radius R. It is displaced through a small distance x from this position and released. The total distance covered before it comes to the bottom and rests there is\[\frac{{{x}^{2}}}{a\mu R}\]. (Coefficient of friction between watch glass surface and the ball is\[\mu \].) Determine a.
