A car of mass m moves around a circular, banked track of radius r and angle of inclination 0, at a velocity vo without sliding, such that there is no frictional force acting on it

A car of mass m moves around a circular, banked track of radius r and angle of inclination 0, at a velocity vo without sliding, such that there is no frictional force acting on it. Explain what would happen to the magnitude and direction of the forces acting on the car if the driver decided to accelerate to increase the speed of the car whilst on the banked track. Is there an upper limit to the speed the driver can accelerate to whilst driving on the banked curve without sliding? Explain your answer. [Hint: new forces may come into play as the car accelerates.
