I have never taken physics before and honestly don't know the best way of learning to solve problems. I am in PHY2053 I understand concepts ok, but have no idea how to go about solving the problems, finding the right equations to solve the problems, or knowing when to use one equation vs...

My teacher in class gave us this equation to solve for the problem: T= 2 pi sqrt. (R/g)(usin theta +cos theta / ucos theta - sin theta) I'm not really sure what u= if i knew i think i could solve the problem. Just to confirm g=9.8 m/s^2 R=11.4 right?

i'm struggling with this same problem except my numbers are a little different my r=11.4, friction is .76 and theta as 36.8. To be completely honest I am in Physics 1 and have no idea how to do physics at all. I understand the concepts, but have a really hard time finding the right equations...
