Hello everyone.(adsbygoogle = window.adsbygoogle || []).push({});

I'm having a little trouble understanding the whole "ball and bowl" problem using Newton's Second Law. What I'm talking about involves a small shpere of mass m and radius r, rolling down a "bowl" (more like a hemisphere of radius R). How would one go about finding the KE of the sphere at the bottom of the hemisphere using Newton's Second Law?

Thanks a lot
