Standards, 3.1.b,c,d , 3.4.c

3. Vector addition
Kim walks 6.5 km at 75 degrees then 8.2 km at 33 degrees. Use the graphical method for addition of vectors to determine her total displacement.
Example problem
Standards, 3.1.b,c,d , 3.4.c

4. Vector addition
Now let’s apply this to a problem. Use the graphical method to find the resultant of the following two displacements:
D1 = 60 m at 40 and
D2 = 40 m at 153
Choose a scale that allows this to fill the entire page.
Assigned problem
Standards, 3.1.b,c,d , 3.4.c

5. Vector addition
Check your answer using “Vector Math” under chapter 3 on the website.
Print this solution and attach it to your graphical solution and place both in your folder.
Standards, 3.1.b,c,d , 3.4.c

6. Wrap it up.
