SUMMARY
The maximum speed a car can maintain while rounding a curve without skidding is determined by the formula v^2 = μσ * g * r, where μσ is the coefficient of static friction, g is the acceleration due to gravity (9.8 m/s²), and r is the radius of the curve (45 m). In this case, with a coefficient of static friction of 0.82, the calculation confirms that the approach is correct. The final speed can be found by taking the square root of the resulting value from the equation.
