Part A - Finding the net friction force Learning Goal: To set up and evaluate the equations motion in a normal-tangential coordinate system. A car of weight 11.1 kN is traveling around a curve of constant curvature p. The car is traveling at a speed of 25.5 m/s, which is increasing at a rate of 2.15 m/s2, and the curvature of the road is p = 170 m. What is the magnitude of the net frictional force that the road exerts on the tires? Express your answer to three significant figures and include the appropriate units. (Figure 1 View Available Hint(s) НА ? F= Value Units Submit Part B - Finding the maximum allowable acceleration Suppose that the tires are capable of exerting a maximum friction force of 3710 N. If the car is traveling at 15.5 m/s and the curvature of the road is p= 140 m, what is the maximum tangential acceleration that the car can have without sliding? Express your answer to three significant figures and include the appropriate units.
