Unformatted text preview: Describe each vector quantity and sketch a picture. 1. A force f of 20 lb at 60 o The angle is measured counterclockwise from the positive xaxis to the vector. The magnitude of the vector is 20. 2. A velocity v of 500 mph at 100 o . The angle, called a heading, bearing, or course is measured clockwise from the north to the velocity vector. 3. Wind velocity w of 10 knots from 200 o The angle is measured clockwise from north to the direction from which the wind is blowing. 4. A displacement OA from O to A of 25 km N30 o W The angle is measured from north (or south) toward west (or east). . 5 2 current...
