Amail carrier parks her postal truck and delivers packages. to do so, she walks east at a speed of 0.80 m/s for 4.0 min, then north at a speed of 0.50 m/s for 5.5 min, and finally west at a speed of 1.1 m/s for 2.8 min. define east as +x and north as +y. (a) write unit-vector velocities for each of the legs of her journey. (b) find unit-vector displacements for each of the legs of her journey. (c) find her net displacement from the postal truck after her journey is complete.
