A butterfly flying with a velocity 4√2 m/s in North-East direction. Wind is slowly blowing at 1 m/s from North to South. The resultant displacement of the butterfly in 3 seconds is:

1. 3m
2. 20m
3. 12√2 m
4. 15m

Correct answer: 15m

Solution

The butterfly's velocity can be broken down into its north and east components, and when combined with the wind's southward velocity, the resultant velocity leads to a net displacement. Over 3 seconds, this results in a total displacement of 15 meters.
