Hunus Group TitleBest ResponseYou've already chosen the best response.3
Just add the components of all of the vectors to find the resultant displacement. First he moves 2.6 km north, then he moves 4 km east then he moves 3.1 km north east.

Okay Nath what is it about this problem that is confusing to you?

The first displacement he moves 2.6 km but he has no horizontal displacement. The second displacement he moves 4 km which is all horizontal. The third displacement he moves 3.1 km which is only part horizontal (You should be able to figure out the horizontal component from the last post)

x=5.7 cos(45) i added the 2.6 to 3.1

Not quite. For the x component 2.6 wouldn't be a part of it because none of it is in the x direction

you mean that 3.1 is not completely horiziontal

Hunus Group TitleBest ResponseYou've already chosen the best response.3
Yes. Also, the component that is 2.6 km is all in the y direction so none of it will be on the x component

How far did the truck travel along the x axis?

What about the 3.1 km he traveled north east? Part of that displacement is along the x axis.

i know to find the x component it would be 3.1 cos(45)

Hunus Group TitleBest ResponseYou've already chosen the best response.3
That's correct :) and that plus the 4 km is how far he moved along the x axis

so i could add the 2.6 to the 3.1 because the 2.6 is completely horizontal while the 3.1 is partially horizontal. however i have to take it into account

The 2.6 is completely vertical. The 4.0 is completely horizontal

Hunus Group TitleBest ResponseYou've already chosen the best response.3
So add up the horizontal parts :)

I'm about to have to head out :/ sorry I couldn't help you finish the problem. Just add up all the x components of all the vectors and all the y components of the vectors and this will create a new vector with the x component you just calculated and the y component you just calculated.
