Problem: A car of mass M = 1100kg traveling at 60.0km/hour enters a banked turn covered with ice. The road is banked at an angle θ, and there is no friction between the road and the car's tires. Use g = 9.80m/s2 throughout this problem.
Part A: What is the radius r of the turn if the angle = 20.0 degrees (assuming the car continues in uniform circular motion around the turn)?
I need expert help to solve the above problem and express your answer in meters.
