BIO Bird Migration. Canada geese migrate essentially along a north-south direction for well over a thousand kilometers in some cases, traveling at speeds up to about 100 km/h. If one goose is flying at 100 km/h relative to the air but a 40-km/h wind is blowing from west to east, (a) at what angle relative to the north-south direction should this bird head to travel directly southward relative to the ground? (b) How long will it take the goose to cover a ground distance of 500 km from north to south? ( Note: Even on cloudy nights, many birds can navigate by using the earth’s magnetic field to fix the north-south direction.)

Canada geese migrate essentially along a north-south direction for well over a thousand kilometers in some cases, traveling at speeds up to about 100 km/h. One goose is flying at 100 km/h relative to the air but a 42 km/h wind is blowing from west to east.
a) At what angle relative to the north-south direction should this bird head to travel directly southward relative to the ground?
b) How long will it take the goose to cover a ground distance of 550 km from north to south? (Note: Even on cloudy nights, many birds can navigate using the earth's magnetic field to fix the north-south direction.)
Canada geese migrate essentially along a north-south direction for well over a thousand kilometers in some cases, traveling at speeds up to about 100 km/h. The one goose is flying at 100 km/h relative to the air but a 50 km/h wind is blowing from west to east.
1) At what angle relative to the north-south direction should this bird head to travel directly southward relative to the ground?
2) How long will it take the goose to cover a ground distance of 550 km from north to south? (Note: Even on cloudy nights, many birds can navigate using the earth's magnetic field to fix the north-south direction.)
An airplane pilot wishes to fly directly westward. According to the weather bureau, a wind of 75.0 km/hourkm/hour is blowing southward. The speed of the plane relative to the air (called the "air speed") as measured by instruments aboard the plane is 310 km/hourkm/hour . In which direction should the pilot head?
a)What is the speed of the air relative to a person standing on the ground, vA/G? What is the speed of the plane relative to the air, vP/A?
