Question

Легковой автомобиль Чайка разгоняешься до скорости 144 км/ч за 4 минуты. Определите ускорение автомобиля.

Answer 1

Ответ:

a=v/t

144км/ч =40м/с

4мин =240с

40/240=0,16м/с²

Answer 2

Calculation of Acceleration

To determine the acceleration of the car, we need to use the formula:

Acceleration (a) = Change in velocity (Δv) / Time taken (Δt)

Given that the car accelerates from 0 km/h to 144 km/h in 4 minutes, we need to convert the time from minutes to seconds and the velocity from km/h to m/s for consistent units.

Converting 4 minutes to seconds: 4 minutes = 4 * 60 seconds = 240 seconds

Converting 144 km/h to m/s: 144 km/h = 144 * (1000/3600) m/s = 40 m/s

Now we can calculate the acceleration: Acceleration (a) = (Final velocity - Initial velocity) / Time taken

Acceleration (a) = (40 m/s - 0 m/s) / 240 seconds

Simplifying the equation: Acceleration (a) = 40 m/s / 240 seconds

Calculating the acceleration: Acceleration (a) = 0.1667 m/s²

Therefore, the acceleration of the car is approximately 0.1667 m/s².

Please note that the search results did not provide specific information about the acceleration of the Chaika car. The calculation above is based on the given information and the assumption that the car accelerates uniformly.
