A delivery truck travels 19 blocks north, 14 blocks west and 15 blocks south. What is its final displacement from the origin?

1915 = 4 north
14 west
sqrt (4^2 + 14^2) = sqrt(212) = 14.6 
since its goes south after ward it is parrelel to north therefore you subtract 19 15 which gives you 4 blocks since that s left over of 19 (u do this to make a triangle to find the displacement) and since 14 blocks is connecting the S and the N it is the ajacent of the triangle and 4 is the base so you do pythagorean theorm and that would be the diplacement. 4(squared)+ 14(squared)=c(squared)
