A 1170-kgkg car and a 2090-kgkg pickup truck approach a curve on the expressway that has a radius of 209 mm. At what angle should the highway engineer bank this curve so that vehicles traveling at 64.3 mi/hmi/h can safely round it regardless of the condition of their tires? Should the heavy truck go slower than the lighter car? As the car and truck round the curve at 64.3 mi/hmi/h, find the normal force on the car to the highway surface. As the car and truck round the curve at 64.3 mi/hmi/h, find the normal force on the truck to the
