A car of mass M = 1100 kg traveling at 40.0 km/hour enters a banked turn covered with ice. The road is banked at an angle 8, and there is no friction between the road and the car's tires as shown in (Figure 1). Use g = 9.80 m/s² throughout this problem. Figure < 1 of 2 ▼ Submit Previous Answers ✓ Correct Correct answer is shown. Your answer 34.61 m was either rounded differently or used a different number of significant figures than required for this part. Important: If you use this answer in later parts, use the full unrounded value in your calculations. Part B Now, suppose that the curve is level (0 = 0) and that the ice has melted, so that there is a coefficient of static friction between the road and the car's tires as shown in (Figure 2). What is min..the minimum value of the coefficient of static friction between the tires and the road required to prevent the car from slipping? Assume that the car's speed is still 40.0 km/hour and that the radius of the curve is 34.6 m. Express your answer numerically. ► View Available Hint(s)
