Many people who have not studied physics might assume that it is impossible for a car to turn in the absence of friction. You known better! If the roadway is banked at exactly the right angle, a car at exactly the right velocity will be put into uniform circular motion and execute the turn successfully. Consider the figure below: R M no friction Here the department of transportation has constructed a roadway that will cause your car to turn in a circle of radius R = 155.5 meters. The roadway itself is banked with an angle of 8 = 18.4 degrees. Assume that your car has a mass of m = 1074 kg. Calculate all the following: The normal force of the road on your car, N The velocity of your car, v m/s The time required to make a 90 degree turn, Newtons S NOTE: For a 90 degree turn, the distance covered is 1/4 of the circumference of the circle.
