1. The problem statement, all variables and given/known data A bowl has a hemispherical inside surface with radius R = 15 cm, and is sitting in the exact center of a spinning table that completes one full turn in 0.72 s. A small marble is dropped into the bowl. After the marble has stopped rolling around, it will come to rest against the inside surface of the bowl, rotating around the center of the table at the same rate as the bowl. You can ignore the size of the marble. The angle θ, as defined in the figure, is closest to ___? DIAGRAM SHOWING THE PROBLEM http://imgur.com/0pKoAKT 2. Relevant equations I guess F=ma a=v^2/r Ff=Fnμ 3. The attempt at a solution No idea how to start even approaching this, sum of all forces?
