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.
