A car of mass M= 1300kg traveling at 40.0 km/hour enters a banked turn covered with ice. The road is banked on an angle (theta) and there is no friction between the road and the cars tires. Use g = 9.80 m/s^2 throughout this problem What is the radius r of the turn if (theta) = 20 degrees. (Assuming the car continues in uniform circular motion around the turn )
