Asked by Jody
A car travels around a curve banked at 45 degrees at 30 m/s. The radius of the track is 40m. What is the resultant force on the driver of the car?

Well, for him, he has mg pushing him up vertically, and in the horizontal, he has a centripetal force of mv^2/r in the horizonal pushing him horizontal.
resultant has to be sqrt(sum of those two forces).
Now why didn't I figure the forces in the coordinate system parallel to the bank? Forces are forces, it would have been the same result, and a lot of unnecessary work.
