Question

A 180 metre long train is moving due north to at a speed of 25m/s. A small
bird is flying due South a little about the train with a shed of 5m/s. The time taken by the bird to Cross the train is​

Answer 1

Answer:

6 seconds

Explanation:

The train in moving due north to at a speed of 25m/s and the bird is moving due the south at a speed of 5m/s.

Using this information we can say that the relative speed between the train and the bird is 30 m/s.

Also the distance to be traveled by the bird is given indirectly as the length of the train so as we know:

Time in relative situation = Distance to be traveled/relative speed

Time=180m/(30m/s)=6seconds
