Question

Визначити шлях гальмування автомобіля при швидкості руху 60 км/год, якщо коефіцієнт тертя дорівнює 0,6.​

Answer 1

Ответ:

Объяснение:

Дано:

v0=60км/год=17м/с

v=0

μ=0,6

S-?

a=μg

S=(v²-v0²)/2a=>

S=v0²/2μg=17²/2*0,6*10=24м

Answer 2

Calculation of Braking Distance

To determine the braking distance of a car at a speed of 60 km/h with a coefficient of friction of 0.6, we can use the formula:

Braking Distance = (Initial Speed^2) / (2 * Acceleration)

The acceleration can be calculated using the formula:

Acceleration = Coefficient of Friction * Gravity

where the coefficient of friction is 0.6 and the acceleration due to gravity is approximately 9.8 m/s^2.

Let's calculate the braking distance step by step:

1. Convert the speed from km/h to m/s: - 60 km/h = 60 * (1000/3600) m/s = 16.67 m/s

2. Calculate the acceleration: - Acceleration = 0.6 * 9.8 m/s^2 = 5.88 m/s^2

3. Calculate the braking distance: - Braking Distance = (16.67^2) / (2 * 5.88) = 140.97 meters

Therefore, the braking distance of the car at a speed of 60 km/h with a coefficient of friction of 0.6 is approximately 140.97 meters.
