Homework Answers
there will be 2 forces acting on the body. One will be weight
along the slope and other will be centrifugal force acting
outwards. balancing both the forces will only result in safe
turning of the vehicle.

A car of mass M = 1500 kg traveling at 65.0 km/hour enters a banked turn covered with ice. The road is banked at an angle ∘, and there is no friction between the road and the car's tires as shown in (Figure 1). 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)?
