Question

Найди тормозной путь легкового автомобиля, если коэффициент трения = 0,05 а начальная скорость = 20 м/с. Найти время торможения

Answer 1

Calculation of Braking Distance

To calculate the braking distance of a car, we need to use the formula:

Braking Distance = (Initial Velocity^2) / (2 * Coefficient of Friction * Acceleration due to Gravity)

Given: - Coefficient of friction (μ) = 0.05 - Initial velocity (v) = 20 m/s

Acceleration due to gravity (g) is approximately 9.8 m/s^2.

Let's substitute the values into the formula and calculate the braking distance:

Braking Distance = (20^2) / (2 * 0.05 * 9.8)

Calculating this expression gives us the braking distance.
