QUESTION:
A seagull flies at a velocity of 9.00 m/s straight into the wind. (a) If it takes the bird 20.0 min to travel 6.00 km relative to the Earth, what is the velocity of the wind? (b) If the bird turns around and flies with the wind, how long will he take to return 6.00 km? (c) Discuss how the wind affects the total round-trip time compared to what it would be with no wind.
ANSWER:
Step 1 of 4
The relative velocity of the seagull relative to the ground is,
\({v_{SG}} = {v_{SA}} + {v_{AG}}\)
\({v_{AG}} = {v_{SG}} - {v_{SA}}\)
Where, \({v_{SG}}\) is velocity of seagull relative to ground, \({v_{SA}}\) is velocity of seagull relative to air, \({v_{AG}}\) is velocity of air relative to ground.
