A dog searching for a bone walks 3.50 m south, then 8.20 m at an angle of 30.0 degrees north of east, and finally 15.0 m west. Use graphical techniques to find the dog's resultant displacement vector. The answer in the back of the book says 7.9 m at 4.3 north of west...

x is your answer , apply sine rule / cos rule or any other faster way , try to find it yourself :)

first, set a scale for your measurements so that you can draw it in your paper using a ruler, example if you scale it 1 cm: 1 m... 3.5 m will be 3.5 cm and use this measurement using the ruler.. don't forget the direction.. do this also on the other measurements.. after that, if you're done.. measure the length of the tail of the first vector, which is the tail of 3.5 m, to the head of the last vector which is the head of 15 m.

  • anonymous
use your protractor to measure the direction between the resultant displacement and the first vector|dw:1378085555325:dw|

hopr you understand.. and if i made a mistake please let me know:)
anonymous
  • anonymous
i still dont understand ! :(
anonymous
  • anonymous
do the steps slowly... and ask a specific question according to the explanation that i did, if you really tried to understand it..
anonymous
  • anonymous
when i draw the vectors do i start from the origin or continue from the last vector?
anonymous
  • anonymous
cm
anonymous
  • anonymous
yes
anonymous
  • anonymous
oh sooryy.. i mean scale..
anonymous
  • anonymous
ok.. then.. how many cm are there in 3.5 m?
anonymous
  • anonymous
350
anonymous
  • anonymous
that's big!! wait i made a mistake! sorry.. we should have a scale of 100 cm: 1m.. ok ? so in 3.5 m we will have also 3.5 cm.. now, using your ruler.. draw a vector which is 3.5cm going south..
anonymous
  • anonymous
okay
anonymous
  • anonymous
did you draw it already?
anonymous
  • anonymous
yes
anonymous
  • anonymous
can you show me a rough sketch?
anonymous
  • anonymous
sorry, its backwards
anonymous
  • anonymous
oh your using NWES plane.. ok your right..good:) but are you allowed not to use that? then
anonymous
  • anonymous
im pretty sure i am, my teacher doesnt care
anonymous
  • anonymous
ok..it's easier for me not to use that.. but i'll try.. so next is to draw the second vector.. draw 8.20 cm from the origin using your ruler and use your protractor to measure the angle(30) from the line of E..
anonymous
  • anonymous
done
anonymous
  • anonymous
i tried to do it.. but it doesn't work graphically using NEWS plane:( because if you will use that, you need to solve it algebraically..
anonymous
  • anonymous
oh okay.
anonymous
  • anonymous
do the same thing that we did, but connect the two vectors head to tail....
anonymous
  • anonymous
it can be done on the same graph right?
anonymous
  • anonymous
no, not that graph.. don't do north,south,west,east graph.. just a blank paper and do the steps we just did..
anonymous
  • anonymous
yeah i got a new paper, but i mean the paper i drew the 8.2 vector from the origin .

anonymous
  • anonymous
okay i did this
anonymous
  • anonymous
now from here do i move 15 m west ?
anonymous
  • anonymous
from the head of the second vector.. don't forget to scale.. after that follow the last step above^ sorry i really need to go now, hope i help you a little bit.. i'll go offline for at least one week..
anonymous
  • anonymous
its okay! thank you for all your help !
