FIGURE P3.25shows vectors A鈫�&B鈫�. Find vector C鈫�such that A鈫�+B鈫�+C鈫�=0鈫�. Write your answer in component form.

Short Answer

Expert verified

The vector isC鈫�=-10.

Step by step solution

01

Step 1. Given information

The following diagram is given

02

Step 2. The vectors

The vectors are

A鈫�=4sin30+4cos60=4B鈫�=3cos20+3sin70=6

Therefore, the third vector is

C鈫�=-(6+4)=-10

II A flock of ducks is trying to migrate south for the winter, but they keep being blown off course by a wind blowing from the west at 6.0m/s. A wise elder duck finally realizes that the solution is to fly at an angle to the wind. If the ducks can fly at 8.0m/srelative to the air, what direction should they head in order to move directly south?

While vacationing in the mountains you do some hiking. In the morning, your displacement is S鈫�morning=(2000m, east )+(3000m, north )+(200m, vertical \()\). After lunch, your displacement is S鈫�afternoon=(1500m, west )+(2000m, north )鈭�(300m, vertical).

a. At the end of the hike, how much higher or lower are you compared to your starting point?

b. What is the magnitude of your net displacement for the day?
