Calculating the time taken by the parrot to cross the train:
To calculate the time taken by the parrot to cross the train, we need to first find the relative velocity of the parrot with respect to the train. Here are the steps to do that:
Step 1: Find the velocity of the train with respect to the ground:
Velocity of train = 10 m/s towards north
Step 2: Find the velocity of the parrot with respect to the ground:
Velocity of parrot = 5 m/s towards south (parallel to the railway track)
Step 3: Find the relative velocity of the parrot with respect to the train:
Relative velocity = velocity of parrot - velocity of train
= 5 m/s - (-10 m/s) (since the parrot is flying towards south and the train is moving towards north)
= 15 m/s
Step 4: Find the distance that the parrot needs to cover to cross the train:
Distance = length of train = 150 m
Step 5: Use the formula: time = distance / speed to find the time taken by the parrot to cross the train:
Time taken = Distance / Relative velocity
= 150 m / 15 m/s
= 10 s
Therefore, the time taken by the parrot to cross the train is 10 seconds (Option A).
