Question

Автомобиль за 2 минуты увеличил скорость с 18 км.ч до 61,2 ки.ч с каким ускорением двигался автомобиль?

Answer 1

43,2 ускорение машины

Answer 2

Calculation of Acceleration

To determine the acceleration of the car, we can use the formula:

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t)

Given: - Initial velocity (u) = 18 km/h - Final velocity (v) = 61.2 km/h - Time (t) = 2 minutes = 2/60 hours = 1/30 hours

Let's calculate the acceleration:

Acceleration (a) = (61.2 km/h - 18 km/h) / (1/30 hours)

Converting the velocities to m/s and the time to seconds:

Acceleration (a) = ((61.2 km/h - 18 km/h) * 1000 m/3600 s) / (1/30 hours * 3600 s)

Simplifying the equation:

Acceleration (a) = ((61.2 - 18) * 1000) / (1/30)

Acceleration (a) = (43.2 * 1000) / (1/30)

Acceleration (a) = 43,200 / (1/30)

Acceleration (a) = 43,200 * 30

Acceleration (a) = 1,296,000 m/s^2

Therefore, the car was moving with an acceleration of 1,296,000 m/s^2.
