When rounding a curve, a car tends to:Options: Speed up. Move to the inside of the curve. Stay in the center of the lane. Move to the outside of the curve.

To help with vehicle stability, the outer edge of a road in a curve is raised with respect to the inner edge. This is called superelevation and is specified as the difference in elevation divided by the width of the road. It needs to be higher for faster speeds and sharper curves.The radius of a curve is the radius of the section of a circle along the middle of the road where the curve is constant. See Figure 1 for a drawing of this.Figure 1: Section of a circle along the middle of a road with radius 𝑅.In some cases the curve may need a lower speed limit than straight portions of the road. The superelevation shouldn’t be more than about .12 to keep vehicles from sliding off the road in slippery conditions.Your job is to calculate the maximum speed on a curve given the radius of the curve and the superelevation.The maximum speed is given by this formula:𝑉=(𝑅∗(𝑆+.16))/.067,where 𝑉 is the max speed in miles per hour, 𝑅 is the radius of the curve in feet, and S is the superelevation.InputThe input is a series of lines terminated by end-of-file. Each line will be a test case consisting of 𝑅 and 𝑆 separated by whitespace. 𝑅 will be an integer greater than 99 and less than 5281 and 𝑆 will be a real number greater than .009 and less than 1.0. Neither will have leading zeros. There are at most 100 lines in input.OutputFor each test case output the maximum speed rounded to the nearest integer. It is guaranteed the answer before rounding will not be within 10−3 of a half-integer value.Sample Input 1 Sample Output 11433 .091433 .122000 .09600 .1273778650

Traffic moves smoothly in a roundabout because vehicles ____ .*1 pointA. Move only to the rightB. Move only to the leftC. Yield instead of stopD. Both A and C

When railroad tracks make a curve, the outer track is longer. This means a wheel that rides on the outer track needs to somehow Group of answer choicesroll faster than the wheel on the inner track.maintain the same speed as the wheel on the inner track.roll slower than the wheel on the inner track.Not any of these will happen because the wheels are balanced

A highway curve has a radius of 817 m. At what angle should the road be banked so that a car traveling at 27.0 m/s (60.4 mph) has no tendency to skid sideways on the road?

When entering an expressway, in the acceleration lane you should: search for a gap in traffic and adjust your speed to the speed of the traffic. set the cruise control for highway speed. make a complete stop and check traffic for a suitable gap. get as close to the vehicle ahead as possible so you can merge into the same gap.
