On а level hоrizоntаl tаble, a tоy race car of mass M moves with a constant speed v around a flat circular racetrack of radius R. The car is now going around a bank curve, as shown in the figure above. The bank curve is higher toward the outside of the circular turn. The car can now travel at a higher speed without sliding because the bank curve:
