A car of mass 1300 travelling at 56.0 enters a banked turn, Ask an Expert

Academics

Q1. A car of mass = 1300 travelling at 56.0 enters a banked turn covered with ice. The road is banked at an angle, and there is no friction between the road and car's tires. What is the radius of the turn if = 20.0 (assuming the car continues in uniform circular motion around the turn)?

Q2. A 150 lb student rides a ferris wheel that rotates at a constant rate. At the highest point, the seat exerts a normal force of magnitude 110 lb on the student. What will the magnitude of this normal force be at the lowest point?
