A car of mass M
= 1200 kg
traveling at 65.0 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 as shown in image. Use g
= 9.80 m/s2
throughout this problem.


What is the radius r
of the turn if θ
= 20.0 ∘
(assuming the car continues in uniform circular motion around the turn)?
