The car moves in a bend in a circle with a radius of 20 m. Determine the maximum speed at which it will make a safe turn if the coefficient of friction of the wheels on the road is 0.5.

To determine the value of the maximum speed of the specified car on the corner, we use the formula: Ftr = μ * m * g = m * ac = m * V ^ 2 / R, from where we express: V = √ (μ * g * R).

Variables and constants: μ – coefficient of friction of the wheels of the specified vehicle on the road (μ = 0.5); g – acceleration due to gravity (g ≈ 10 m / s2); R is the radius of the circle at the turn (R = 20 m).

Let’s calculate: V = √ (μ * g * R) = √ (0.5 * 10 * 20) = 10 m / s.

Answer: The maximum speed of the specified vehicle on a bend should not exceed 10 m / s.
