Question

СРОЧНО!!!!!!!!!!!!! Задача 54. Поїзд через 10 с після початку руху набуває швидкості0.6M / c . Через який час від початку руху швидкість поїзда буде дорівнювати 3M /

Answer 1

Ответ:

50 секунд

Объяснение:

ускорение (а) = 0,6/10=0,06 м/с²

t=3/0,06=50с

Answer 2

Problem 54: Train Speed Calculation

To solve this problem, we need to determine the time it takes for the speed of the train to reach 3 m/s, given that it starts with an initial speed of 0.6 m/s and accelerates at a constant rate.

Let's break down the problem and solve it step by step.

Given:

- Initial speed of the train: 0.6 m/s - Target speed of the train: 3 m/s

Approach:

To find the time it takes for the train to reach the target speed, we can use the formula for uniform acceleration:

v = u + at

Where: - v is the final velocity (3 m/s in this case) - u is the initial velocity (0.6 m/s in this case) - a is the acceleration (which we need to find) - t is the time taken

Rearranging the formula to solve for time (t), we get:

t = (v - u) / a

Calculation:

Substituting the given values into the formula, we have:

t = (3 m/s - 0.6 m/s) / a

Now, we need to find the acceleration (a). Unfortunately, the problem statement does not provide the acceleration directly. Therefore, we cannot provide a specific answer without additional information.

Please provide the value of acceleration (a) so that we can calculate the time it takes for the train to reach the target speed of 3 m/s.

If you have any additional information or if there is anything else I can help you with, please let me know!
