U3 - CIRCULAR MOTION AND ORBITS PROBLEM SET 3. A car of massm = 1300 kg traveling at 55.0 km/hour enters a banked turn covered with ice. The road is banked at an angle 0, and there is no friction between the road and the car's tires. Use g = - 9.80 m/s? throughout this problem. What is the radius r of the turn if 0 = 20.0° (assuming the car continues in uniform circular motion around the turn)?
