**Educational Text and Diagram Explanation** A certain vehicle moves at a constant speed of 50.0 mph as it rounds a horizontal unbanked curve with a radius of curvature of 0.100 km. The problem is to determine the maximum speed in mph at which this car can safely round a second horizontal unbanked curve with a radius of 0.150 km, assuming the coefficient of static friction (µₛ) between the vehicle's tires and the road surface remains unchanged. Follow the outlined steps to solve the problem. Note that we will complete the Free Body Diagram (FBD) of the car together in class. (Note: 1609 m = 1 mile). **Steps to Solve:** (a) **GFS Method:** Use the Given-Find-Solution method to show and explain each step in your work. (b) **Sketch and FBD:** Draw a sketch of the vehicle rounding an unbanked curve. Include a Free Body Diagram (FBD) that represents all external forces acting on the vehicle. Label each force clearly and use a designated x and y coordinate system. (c) **Newton's Second Law Equations:** Write the standard equations for Newton’s Second Law for the first curve. Clearly associate these equations with designated variables (e.g., v₁ and r₁). Simplify the equations using the given information to solve for the coefficient of static friction (µₛ) to three significant figures. (d) **Modify and Solve for Second Curve:** Adapt the Second Law equation from step (c) to represent the second curve (e.g., v₂ and r₂) and solve for the new speed v₂, expressing the answer in mph to three significant figures. **Choices for Maximum Speed:** - 38.0 mph - 32.4 mph - 61.1 mph - 18.0 mph - 43.0 mph **Image Explanation:** The image shows a winding, unbanked road with lush greenery on both sides, typical of a scenario used to describe real-world applications of physics concepts such as centripetal force and friction. The road signifies the type of curve being described in the problem for visual reference.

Transcribed Image Text:**Educational Text and Diagram Explanation**
A certain vehicle moves at a constant speed of 50.0 mph as it rounds a horizontal unbanked curve with a radius of curvature of 0.100 km. The problem is to determine the maximum speed in mph at which this car can safely round a second horizontal unbanked curve with a radius of 0.150 km, assuming the coefficient of static friction (µₛ) between the vehicle's tires and the road surface remains unchanged. Follow the outlined steps to solve the problem. Note that we will complete the Free Body Diagram (FBD) of the car together in class. (Note: 1609 m = 1 mile).
**Steps to Solve:**
(a) **GFS Method:** Use the Given-Find-Solution method to show and explain each step in your work.
(b) **Sketch and FBD:** Draw a sketch of the vehicle rounding an unbanked curve. Include a Free Body Diagram (FBD) that represents all external forces acting on the vehicle. Label each force clearly and use a designated x and y coordinate system.
(c) **Newton's Second Law Equations:** Write the standard equations for Newton’s Second Law for the first curve. Clearly associate these equations with designated variables (e.g., v₁ and r₁). Simplify the equations using the given information to solve for the coefficient of static friction (µₛ) to three significant figures.
(d) **Modify and Solve for Second Curve:** Adapt the Second Law equation from step (c) to represent the second curve (e.g., v₂ and r₂) and solve for the new speed v₂, expressing the answer in mph to three significant figures.
**Choices for Maximum Speed:**
- 38.0 mph
- 32.4 mph
- 61.1 mph
- 18.0 mph
- 43.0 mph
**Image Explanation:**
The image shows a winding, unbanked road with lush greenery on both sides, typical of a scenario used to describe real-world applications of physics concepts such as centripetal force and friction. The road signifies the type of curve being described in the problem for visual reference.
