1. The problem statement, all variables and given/known data
Please refer to both figures. The result of the example problem was θ=33.2°

2. Relevant equations
ΣFn=man

3. The attempt at a solution
I am stumped. I thought you could solve the forces in the z direction, straight up from the car, and set that to zero since there is no acceleration in that direction. Then maybe sum the forces in the normal direction that is perpendicular to the ground and to the left in this case. Please help!!

Have you considered the centripetal force and it's Components?

Once you draw all the forces acting on the block I suggest to scompose the forces on the perpendicular and parallel directions to the plane

I figure it out. I had I a sign wrong and that was throwing me off. Thanks for your help though.
