A car of mass M = 1300 kilogram traveling at 60.0 km/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.
Determine the radius r of the turn if θ = 20.0 degree. (Assuming the car continues in uniform circular motion around the turn)?
