Question

Поезд разгоняется из состояния покоя с ускорением 0,066 м/с2. Какой скорости достигнет поезд за 6 мин?

Answer 1

Ответ:

23,76 м/c

Объяснение:

a=0.066 м/с²    t=360 c    v=?

===

vo=0

v=vo+a*t=0+0.066*360=23.76 м/с

===============================

Answer 2

Calculation of the Train's Final Velocity

To calculate the final velocity of the train, we can use the equation of motion:

v = u + at

Where: - v is the final velocity - u is the initial velocity (which is zero in this case, as the train starts from rest) - a is the acceleration - t is the time taken

Given that the acceleration of the train is 0.066 m/s^2 and the time taken is 6 minutes, we need to convert the time to seconds before plugging the values into the equation.

1 minute = 60 seconds

Therefore, 6 minutes is equal to 6 * 60 = 360 seconds.

Now, let's calculate the final velocity of the train:

v = 0 + (0.066 m/s^2) * 360 s

Calculating this, we find:

v = 23.76 m/s

Therefore, the train will reach a final velocity of 23.76 m/s after 6 minutes of acceleration.
