You are assigned to design the slope of turns on a highway. The proper slope is such that at the target speed for the highway, sideways friction on the tires is not needed for vehicles to make the turn. In the picture is shown the rear view of a bus going through one of these turns. Assume the angle of the slope is 9.95 degrees and the radius of the turn is R = 142 m. What is the target speed for this turn? Give your answer in m/s to three significant figures.
