Solve the all parts of given question:

Question: A 1260-kg car and a 2020-kg tow truck approach a curve on the expressway that has a radius of 235m.

Part A: At what angle should the highway engineer bank this curve so that vehicles traveling at 57.4mi/h can safely round it regardless of the condition of their tires?

Part B: As the car and tow truck round the curve at 57.4mi/h, find the normal force on the car to the highway surface.

Part C: As the car and tow truck round the curve at 57.4mi/h, find the normal force on the truck to the highway surface.

I need help to find the normal force on the truck to the highway surface.
