Hey, I'm really having problems with this question and I don't really know what to do. I'm hoping someone can help me. Thanks in advance.
A highway curves to the left with radius of curvature R = 35 m. The highway's surface is banked at 19 degrees so that the cars can take this curve at higher speeds.
Consider a car of mass 907 kg whose tires have static fiction coefficient of .72 against the pavement.
The acceleration of gravity is 9.8 m/s^2.
How fast can the car take this curve without skidding to the outside of the curve? Answer in units of m/s.
(mv^2)/r = Fn Sin(angle)
mg = Fn Cos (angle)
(v^2)/rg = Tan (angle)
Ac = g tan (angle)
