## Homework Statement

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 38 km/h -km/h wind is blowing from west to east.

At what angle relative to the north-south direction should this bird head to travel directly southward relative to the ground?

## Homework Equations

basic vector addition and components , distance formula

## The Attempt at a Solution

1 vector E to W 38

1 vector S to N 100

the angle of the resulting vector is arctan 38/100 =20.806 N of E

90-20.806 = 69.19 W of N

How is this not right? this is simple vector stuff which I know well.
