Chapter 12, Problem 50(choose chapter or problem)
Circular Motion In Exercises 49 and 50, use the results of Exercises 45-48.
A 3400-pound automobile is negotiating a circular interchange of radius 300 feet at 30 miles per hour (see figure). Assuming the roadway is level. find the force between the tires and the road such that the car stays on the circular path and does not skid. (Use F = ma, where m = 3400/32.) Find the angle at which the roadway should be banked so that no lateral frictional force is exerted on the tires of the automobile.
