1. The problem statement, all variables and given/known data A curve of radius 78 m is banked for a design speed of If the coefficient of static friction is 0.30 (wet pavement), at what range of speeds can a car safely make the curve? 2. Relevant equations 3. The attempt at a solution I calculated theta being 36.1... (85/3.6)^2/78=gTan(theta) Now, I'm wondering how to calculate the range of acceptable velocitys.. could someone explain it to me. I think for max velocity the centripetal force = Sliding force + Frictional force = 104kph correct? Can explain how I need to think for minimum velocity?
