Hi everyone, I just need some help on setting up a free body diagram with the appropriate forces acting on it. The question is: An engineer must design a curved exit ramp for a highway in such a way that a car, exiting at the posted speed limit of 17.88 m/s (40 mi/hr), does not depend on friction to round the curve without skidding. The radius of the curve is 208.0 m. At what angle with respect to the horizontal must the curve be banked (in degrees)? I m confused as to whether to draw the angle theta with respect to the x-axis or y-axis? I already got the answer I am just reviewing for a test I am having. Thank you!
