1) A concrete highway curve of radius 70 m and is banked at an angle of 30o. Imagine a car driving around the turn at a constant height. We want to find the maximum speed at which a 1100 kg rubber-tired car can go around this curve. Take the static coefficient of friction of rubber on concrete to be ?s = 1.0. a) Calculate the maximum speed the car can go around the curve. b) Discuss what is different from...
