A 1128 kg car and a 2210 kg pickup truck approach a curve, Ask an Expert

Academics

A 1128 kg car and a 2210 kg pickup truck approach a curve on the expressway that has a radius of 272 m.

A) At what angle should the highway engineer bank this curve so that vehicles traveling at 72.9 can safely round it regardless of the condition of their tires?

B) As the car and truck round the curve at 72.9 mi/hr , find the normal force on the car to the highway surface (in N).

C) As the car and truck round the curve at 72.9 mi/hr, find the normal force on the truck to the highway surface (in N).
