John rows his canoe due east across a river at 5.5 miles per hour. If the river is flowing south at 4 miles per hour, find John’s direction.
-------------
His velocity is the vector addition of the 2 input vectors.
The angle = atan(4/5.5) =~ 36 degs from East
East is 090 degs
His direction is 126 degs, more or less southeast.
