The Attempt at a Solution
I'm somewhat stuck. I would like to answer the problem myself, but guidance towards the correct methods would be greatly appreciated. I am confused on how to decide which forces and vectors should be used. I also am confused on how to calculate the normal forces. Any help is appreciated.
