Car traveling along the "reverse" banked turn (road tilted away from the curvature). Radius of curvature is 15 m, static friction between road and tires is 0.5, and banking angle is 10 degrees. Find the maximum velocity possible on this reverse banked turn.
The Attempt at a Solution
sqrt(0.5 x 9.8 x 15)= 8.57 m/s
Its wrong as actual answer is 7.2m/s
