A car of mass M = 900kg traveling at 50.0km/hour 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 g = 9.80m/s2 throughout this problem. What is the radius r of the turn if ? = 20.0? (assuming the car continues in uniform circular motion around the turn)?
