(a) Determine the magnitude and direction (relative to due west) of the bird watcher's displacement. Use kilometers and hours for distance and time, respectively.

(b) Determine the magnitude and direction (relative to due west) of the bird watcher's average velocity.

**Damon**, Sunday, September 5, 2010 at 7:07pmn = North component = -.6 + 2.7 sin 37

w = West component = -.45 + 2.7 cos 37

magnitude^2 = n^2 + w^2

direction north of west = tan^-1 (n/w)

ns = north speed = n/4

ws = west speed = w/4

now do the same thing for magnitude of velocity

the angle for velocity is the same as for displacement (top and bottom both divided by 4)
