A 1280- car and a 2250- pickup truck approach a curve on the expressway that has a radius of 204 .
a) At what angle should the highway engineer bank this curve so that vehicles traveling at 59.1 can safely round it regardless of the condition of their tires?
b) As the car and truck round the curve at 59.1 , find the normal force on the car to the highway surface.
c) As the car and truck round the curve at 59.1 , find the normal force on the truck to the highway surface.
