Question

Паспжир поезда идущего со скорочтью15м/с видит в окне встречный поезддлинной 150 м в течение 6с. какова скорость встречного поезда

Answer 1

1)150:6=25-метров 
Ответ:25 м/с едет встречный поезд

Answer 2

Скорость поездов относительно друг друга равна v+15=150/6=25м/с

скорость встречного поезда 25-15 = 10 м/с

Ответ: 10 м/с скорость встречного поезда

Answer 3

Calculation of the Speed of the Oncoming Train

To calculate the speed of the oncoming train, we can use the formula:

Relative Speed = Speed of Train A + Speed of Train B

In this case, the passenger is on a train moving at a speed of 15 m/s, and they observe an oncoming train that is 150 m long passing by in 6 seconds. We need to find the speed of the oncoming train.

Let's calculate the relative speed using the given information:

Speed of Train A (Passenger's Train) = 15 m/s

Length of Train B (Oncoming Train) = 150 m

Time taken to pass the passenger = 6 seconds

Using the formula, we can calculate the relative speed:

Relative Speed = Speed of Train A + Speed of Train B

Relative Speed = (Length of Train B) / (Time taken to pass the passenger)

Relative Speed = 150 m / 6 s

Relative Speed = 25 m/s

Therefore, the speed of the oncoming train is 25 m/s.
