A car of mass = 1200kg traveling at 55.0km/hr 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. (Figure 1) . Use g = 9.80 m/s2 throughout this problem. What is the radius r of the turn if angle= 20.0 (assuming the car continues in uniform circular motion around the turn)? answer in meteres.
