Part A A car of mass M = 1200 kg traveling at 55.0 km/hour enters a banked turn covered with ice. The road is What is the radius r of the turn if 0 = 20.0 (assuming the car continues in uniform circular motion around the turn)? banked at an angle 0, and there is no friction between the road and the car's tires as shown in (Figure 1). Use g Express your answer in meters. =9.80 m /s2 throughout this problem. View Available Hint(s) r = 65.4 m Submit Previous Answers Correct 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 55.0 km/hour and that the radius of the curve is 65.4 m . Express your answer numerically.
