A car drives over the top of a hill that has a radius of 50m. What maximum speed can the car have without flying off the road at the top of the hill? 2) (10 points) You are driving your car through a roundabout that has a radius of 9.0m. Your physics textbook is on the seat next to you. What is the fastest speed at which you can go around the curve without the book sliding? Coefficient of static friction between book and the seat is 0.30. 3) (10 points) The space shown below provides artificial gravity of g for its occupants. It is 200m in diameter. How much time does the station take to complete one rotation?
