AI Generated Solution

To find the maximum speed a car can take on a level turn without skidding, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Given Values**: - Radius of the turn (r) = 45 m - Coefficient of static friction (μ) = 2.0 - Acceleration due to gravity (g) = 10 m/s² (approximate value) ...
