civil engineer wishes to redesign the curved roadway in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when the road is covered with ice. Such a ramp is usually banked, which means that the roadway is tilted toward the inside of the curve. Suppose the designated speed for the ramp is to be 10.0 m/s and the radius of the curve is 20.0 m. At what angle should the curve be banked? A 30° Ⓡtan¹ B 60° tan-1! civil engineer wishes to redesign the curved roadway in such a way that a car will not have to rely on friction to round the curve without skidding.
