A girl delivering newspapers cover her route by traveling 2 blocks west, 4 blocks north, then 9 blocks east.
a) What is her resultant displacement?

b) What is her direction? Use counterclockwise as the positive angular direction from due east, between the limites of -180 degrees and 180 degrees.

c)What is the total distance she travels?

I really need this answer please
 
Physics news on Phys.org
try to draw it on graph paper.
 
I cannot figure out the displacement either way
does anyone know what it is?
 
I'll tell you that you will need to find the hypotenuse of a triangle.
If you draw it out, you'll be able to see the triangle. (You'll have to subtract something to see it.)
