A car of mass = 800 traveling at 65.0 enters a banked turn covered with ice. The road is banked at an angle , and there is no friction between the road and the car's tires. Use = 9.80 throughout this problem. What is the radius of the turn if = 20.0 (assuming the car continues in uniform circular motion around the turn)?
