A roadway is designed for traffic moving at a speed of 66m/s. A curved section of the roadway is in the shape of a circular arc of 290-m radius. This section of roadway is banked so that a vehicle travelling at 66m/s will experience no net lateral acceleration. What is the angle at which the roadway is banked? 57 degrees 51 degrees 53 degrees 55 degrees 59 degrees​
