A train of 150 metre long is going towards north direction at a speed ...
To solve this problem, we need to determine the time taken by the parrot to cross the train. Let's break down the problem into smaller steps:
Step 1: Calculate the relative velocity of the parrot with respect to the train.
Since the parrot is flying towards the south direction while the train is moving towards the north direction, their velocities are opposite in direction. Therefore, we can subtract the velocity of the train from the velocity of the parrot to find the relative velocity of the parrot with respect to the train.
Relative velocity = Parrot's velocity - Train's velocity
Relative velocity = 5 m/s - (-10 m/s) [Negative sign for the train's velocity since it is in the opposite direction]
Relative velocity = 5 m/s + 10 m/s
Relative velocity = 15 m/s
Step 2: Calculate the time taken by the parrot to cross the train.
The parrot is flying parallel to the railway track, so the distance it needs to cover to cross the train is equal to the length of the train, which is 150 meters.
Time = Distance / Relative velocity
Time = 150 m / 15 m/s
Time = 10 seconds
Thus, the parrot takes 10 seconds to cross the train.
Therefore, the correct answer is option D) 10 seconds.
Step 1: Calculate the relative velocity of the parrot with respect to the train.
Since the parrot is flying towards the south direction while the train is moving towards the north direction, their velocities are opposite in direction. Therefore, we can subtract the velocity of the train from the velocity of the parrot to find the relative velocity of the parrot with respect to the train.
Relative velocity = Parrot's velocity - Train's velocity
Relative velocity = 5 m/s - (-10 m/s) [Negative sign for the train's velocity since it is in the opposite direction]
Relative velocity = 5 m/s + 10 m/s
Relative velocity = 15 m/s
Step 2: Calculate the time taken by the parrot to cross the train.
The parrot is flying parallel to the railway track, so the distance it needs to cover to cross the train is equal to the length of the train, which is 150 meters.
Time = Distance / Relative velocity
Time = 150 m / 15 m/s
Time = 10 seconds
Thus, the parrot takes 10 seconds to cross the train.
Therefore, the correct answer is option D) 10 seconds.
