please help with part b

image text in transcribed
What is the radius r of the turn if 0 = 20.0 * (assuming the car continues in uniform circular motion around the A car of mass M = 900 kg traveling at 65.0 km/hour turn)? enters a banked turn covered with ice. The road is banked Express your answer in meters. at an angle 0, and there is no friction between the road and the car's tires as shown in (Figure 1). Use g =9.80 View Available Hint(s) m/s' throughout this problem. r = 91.4 m Submit Previous Answers Correct Figure 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 65.0 km/hour and that the radius of the curve is 91.4 m . Express your answer numerically. View Available Hint(s) Amin =
