2. A delivery man starts at the post office, drives 40 km north, then 20 km west, then 60 km northeast, and finally 50 km south to stop for lunch. Assume i points East, and ĵ point North. Use the analytical method (adding vector components) when answering the following. (a) Sketch the four displacement vectors, and the net displacement. (b) Find his net displacement vector, Ar. Express in vector notation. (c) How far is the restaurant from the post office? (d) If he returns directly from the restaurant to the post office, what is his displacement vector on the return trip? (e) What is his compass heading on the return trip? (For example, a compass heading could be stated as 10° North of East.)
