Chapter 3: Q. 1 (page 77)

Trace the vectors in FIGURE EX3.1 onto your paper. Then find.

(a)A→+B→and (b)A→-B→.

Short Answer

Expert verified

(a) A→+B→=A1+B1,A2+B2.

(b)A→-B→=A1-B1,A2-B2.

Step by step solution

01

Part (a) Step 1. Given information

The given figure is, dds

We need to trace the figure and determineA→+B→.

02

Step 2. Calculationk

By vector addition,

A→+B→=A1+B1,A2+B2.

03

Part (b) Step 1. Given information

The given figure is,

We need to trace the figure and determineA→-B→.

04

Step 2. Calculation

By vector subtraction,

A→-B→=A→+-B→.

=A1-B1,A2-B2.

The treasure map in FIGURE P3.40 gives the following directions to the buried treasure: "Start at the old oak tree, walk due north for 500 paces, then due east for 100 paces. Dig." But when you arrive, you find an angry dragon just north of the tree. To avoid the dragon, you set off along the yellow brick road at an angle 60°east of north. After walking 300 paces you see an opening through the woods. Which direction should you go, and how far, to reach the treasure?
