A car of mass M = 1000kg traveling at 60.0km/hour enters a banked turn covered with ice. The road is banked at an angle theta, and there is no friction between the road and the car's tires.. Use g = 9.80m/s^2 throughout this problem. What is the radius (r) of the turn if theta = 20.0 degrees (assuming the car continues in uniform circular motion around the turn)?
