Problem: Race tracks are "banked" so that cars may travel faster around curves. Consider the situation described in problem 5), but bank the track at 15°. That is along the radial direction the track slopes downward toward the circle's center at 15°.
Part A: What is the maximum speed the car can have without the tires slipping?
I need help to find the maximum speed the car can have without the tires slipping.
