1. The problem statement, all variables and given/known data 9. A 2000 kg car is racing around a banked circular path whose radius of curvature is 50.0m. The coefficient of static friction between the car and the road is 0.100. What is the maximum possible speed for the car to remain on the road if the angle of the curve is 15°? a) 45.7 km/h b) 49.0 km/h c) 60.0 km/h d) 130 km/h e) 197 km/h 2. Relevant equations Fsmax = Us FN FN = cos15mg Fc = mV^2/r 3. The attempt at a solution Once again stuck on another problem. From what I see, there is a component of the normal force that points towards the center of the radius as well as a component of the static friction that points towards the center of the circle. These two values added should give me the centripetal force, if I am right. Assuming this is true this is what I have tried. sin15(cos15)mg= X component normal force pointing towards center Us(cos15mg)(cos15)= x component of FsMax that points towards center sin15(cos15)mg + Us(cos15mg)(cos15) = Fc Fc=mv^2/r divide the equation by mass sin15(cos15)g + Us(cos15g)(cos15) = v^2/r multiply the left side by r and root for velocity Root([(sin15)(cos15)g + Us(cos15g)(cos15)]r) = v v = 12.96m/s What am I missing here? I have a midterm tomorrow please answer as soon as you can thank you.
