Newtons law of motion, i am stuck please help. It is about trying to find radius and friction force.

D1 1 1|A75%1 . ) A car of mass M = 1000 kg traveling at 65. 0 km/ hour enters a banked turn covered with ice . The road isbanked at an angle , and there is no friction between the road and the car's tires as shown in Figure .Use 9 = 9.80 m/s ? throughout this problem ."\- - - - - - - - -20 0 0 0-a) What is the radius , of the turn if @ = 20.0. ( assuming the car continues in Uniform circular motionaround the turn ) ? Express your answer in meters .b) Now , suppose that the curve is level ( 0 = 0 ) and that the ice has melted , so that there is a coefficient ofstatic friction " between the road and the car's tires as shown in Figure .What is , the minimum value of the coefficient of static friction between the tires and the road required to preventthe car from slipping ? Assume that the car's speed is still 65. 0 km/ hour and that the radius of the curve is 91 .4m .
