### Question on Roadway Design**Problem Statement:**What is the coefficient of side friction for a horizontal curve with a design speed of 70 mph?*(Textbox for answer submission follows)*---**Explanation:**This question pertains to the design of horizontal curves on roadways. The coefficient of side friction is a critical factor considered in roadway design to ensure safety, especially on curves. It represents the frictional resistance between the tires of a vehicle and the roadway surface, which helps vehicles maintain control as they navigate through a curve.In practical application, the design speed is the speed at which vehicles are expected to travel on a specific section of the roadway under normal conditions. *Please provide your answer in the text box below.*---**Imagine If There Were Graphs or Diagrams:**If the image contained graphs or diagrams, we would expect to see representations such as:1. **Graph of Coefficient of Friction vs. Speed**: A plot illustrating how the coefficient of side friction changes with varying speeds. 2. **Diagram of a Horizontal Curve**: A schematic showing a vehicle navigating a horizontal curve, indicating forces at play, including frictional force, centrifugal force, etc.If there were such diagrams, they would assist in visually understanding the relationship between speed and the coefficient of friction and the physical dynamics of navigating a curve.---For any further queries or discussion, feel free to use the comments section below.

2.20 A driver is traveling at 90 mi/h down a 3% grade on good, wet pavement. An accident investigation team noted that braking skid marks started 410 ft before a parked car was hit at an estimated 45 mi/h. Ignoring air resistance, and using theoretical stopping distance, what was the braking efficiency of the car? (Mannering 53) Mannering, Fred L., Scott Washburn.
