Homework Equations
The Attempt at a Solution
First I drew the picture:
EDIT: Attachment
Then I solved the relative velocity formula:
[itex]v_{w/g} = v_{s/g} + v_{w/s}[/itex] = 23 + 3 = 26mi/h
Which went wrong, so I made another attempt:
[itex]\sqrt{23^2 + 3^2} = 23.2[/itex]
And i don't know how to find the angle. Should I do it like arctan(23/3) ?
Thanks in advance,
