Chapter 3: Q. 26 (page 78)

FIGURE P3.26shows vectors A鈫�&B鈫�. Find D鈫�=2A鈫�+B鈫�. Write your answer in component form.

Short Answer

Expert verified

The value ofD鈫�=42+3+2-3.

Step by step solution

01

Step 1. Given information

The following diagram is given

02

Step 2. The vector calculation

The vectors are

A鈫�=2sin15+2cos75=22-3B鈫�=4cos15+4sin75=42+3

Hence,D鈫�=2A鈫�+B鈫�=42+3+42-3=42+3+2-3
