A car merges onto the freeway on a banked curve. The car
maintains a constant velocity 푣 while driving on the curve, which
is banked at angle theta and has a radius of curvature R. The car
has mass m and the coefficient of static friction between the car’s
tires and the road is meu(s). What is the maximum and minimum speed
that the car can go around the banked curve without slipping? Hint:
The car tends to slip up...
