. I do not know how to solve this problem. I need some help. How would we find out A, the angle between the horizontal and the fuel level line inside the tank of a car?. The car speed does not change, let´s say 60 km/hr, but we are driving in a roundabout. So, the fuel inside the tank will be displaced to the right due to the centrifugal force (in England it will go to the left). Lets imagine that car body is horizontal and not affected by the curve. (see attached pic). We know the car speed and the radius of the car turn. Can we determine angle A?. Will it depend on how much the tank is filled ? any other variable ? Thank you very much in advance and Merry Christmas.
