351 kg race car is rounding a curve in the road which is banked at an angle of 13.2 degrees from the horizontal. Assume that there has just been a massive snowfall and the road’s surface is frictionless. What must the radius of the curve be if the car is travelling at a speed 12.1 m/s and yet stays on the road?
